This chapter consists of the application of molecular orbital theory to the bonding in triatomic molecules, with its extension to the factors responsible for the determination of bond angles and molecular shapes.

These factors should be considered when studying spectra as they can result in important changes to the spectra and may result in the misinterpretation of bands. Overtone bands in an infrared spectrum are analogous and are multiples of the fundamental absorption frequency.

    The energy levels for overtones of infrared modes are illustrated in Figure 1.

When an overtone or a combination band has the same frequency as, or a similar frequency to, a fundamental, two bands appear, split either side of the expected value and are of about equal intensity. The effect is greatest when the frequencies match, but it is also present when there is a mismatch of a few tens of wavenumbers. The two bands are referred to as a Fermi doublet. Such vibrations are not restricted to one or two bonds, but may involve a large part of the carbon backbone and oxygen or nitrogen atoms if present.

      The energy levels mix, hence resulting in the same number of vibrational modes, but at different frequencies, and bands can no longer be assigned to one bond. This is very common and occurs when adjacent bonds have similar frequencies. A further requirement is that to be strongly coupled, the motions must be in the same part of the molecule. This type of structure is due to the excitation of rotational motion during a vibrational tran- sition and is referred to as an vibration—rotation spectrum [1]. The absorptions fall into groups called branches and are labelled P, Q and R according to the change in the rotational quantum number associated with the transition.

      The sep- aration of the lines appearing in a vibration—rotation spectrum may be exploited to determine the bond length of the molecule being examined. Summary The ideas fundamental to an understanding of infrared spectroscopy were intro- duced in this chapter. The electromagnetic spectrum was considered in terms of various atomic and molecular processes and classical and quantum ideas were introduced. The vibrations of molecules and how they produce infrared spectra were then examined.

      The various factors that are responsible for the position and intensity of infrared modes were described.

      Factors such as combination and overtone bands, Fermi resonance, coupling and vibration—rotation bands can lead to changes in infrared spectra. An appreciation of these issues is important when Introduction 13 examining spectra and these factors were outlined in this chapter. For further reference, there is a range of books and book chapters available which provide an overview of the theory behind infrared spectroscopy [3—7]. References 1. Atkins, P. Vincent, A.

      Meaning of "triatomic" in the English dictionary

      Eds , Wiley, Chichester, UK, , pp. Barrow, G. This Page Intentionally Left Blank In recent decades, a very different method of obtaining an infrared spectrum has superceded the dispersive instrument. Fourier-transform infrared spectrometers are now predominantly used and have improved the acqui- sition of infrared spectra dramatically. In this present chapter, the instrumentation required to obtain an infrared spectrum will be described. Infrared spectroscopy is a versatile experimental technique and it is relatively easy to obtain spectra from samples in solution or in the liquid, solid or gaseous Infrared Spectroscopy: Fundamentals and Applications B.

      In this chapter, how samples can be introduced into the instrument, the equipment required to obtain spectra and the pre-treatment of samples are exam- ined. First, the various ways of investigating samples using the traditional trans- mission methods of infrared spectroscopy will be discussed. Infrared spectroscopy has also been combined with other well-established analyt- ical techniques such as chromatography and thermal analysis.

      Such combination techniques are introduced here. The popularity of prism instruments fell away in the s when the improved technology of grating construction enabled cheap, good- quality gratings to be manufactured. The dispersive element in dispersive instruments is contained within a monochromator. Figure 2. The dispersed spectrum is scanned across the exit slit by rotating a suitable component within the monochromator. The widths of the entrance and exit slits may be varied and programmed to compensate for any variation of the source energy with wavenumber.

      In the absence of a sample, the detector then receives radiation of approximately constant energy as the spectrum is scanned. Atmospheric absorption by CO2 and H2O in the instrument beam has to be considered in the design of infrared instruments. These contributions can be taken into account by using a double-beam arrangement in which radiation from a source is divided into two beams.

      These beams pass through a sample and a reference path of the sample compartment, respectively. The information from these beams is rationed to obtain the required sample spectrum. A detector must have adequate sensitivity to the radiation arriving from the sample and monochromator over the entire spectral region required. Sources of infrared emission have included the Globar, which is constructed of silicon carbide.

      Most detectors have consisted of thermocouples of varying characteristics. CO2 and H2O. This contains narrow slits at the entrance and exit which limit the wavenumber range of the radiation reaching the detector to one resolution width.

      Samples for which a very quick measurement is needed, for example, in the eluant from a chromatography column, cannot be studied with instruments of low sensitivity because they cannot scan at speed. However, these limitations may be overcome through the use of a Fourier-transform infrared spectrometer.
