Absorption Measurements

With the advent of a variety of tunable infrared lasers, high resolution spectroscopy in this region has received a great boost. In particular the high power spin flip Raman laser is an excellent tool for very high resolution spectroscopy of ground state as well as excited states of molecules, saturation spectroscopy of molecules and two-photon Doppler-free spectroscopy of molecules. In addition, the use of opto-acoustic techniques for absorption measurements in conjunction with the spin flip Raman laser is capable of measuring absorption coefficients as small as 10 -10 cm -1 . This ability has been of importance in the detection of minor constituents in the atmosphere and the stratosphere. This paper reviews some of these interesting investigations.

Carbonyl Sulphide

Frequency calibration and linewidth measurements of the c.w. spin-flip Raman laser (s.f.R.l.) over the range 1905-1850 cm- 1 have been afforded by molecular spectroscopy of the gases carbonyl sulphide, nitric oxide, deuterium bromide and water vapour. Opto-acoustic detection, made possible by the large spectral brightness of the s.f.R.l. (some 10 10 times above th at of a conventional black body source), was shown to be a particularly useful technique. Two regimes of operation of the c.w. s.f.R.l. were investigated. In the spin-saturated regime the output was continuously tunable to within 100 MHz, with a linewidth of ca . 300 MHz, whereas in the cavity mode limited regime the output exhibited discontinuous tuning characterized by mode pulling effects, but with a linewidth some two orders of magnitude lower. A complete band analysis of several vibration-rotation transitions in carbonyl sulphide was made the results agreeing well with previous data. This showed that even with its poorest resolution the c.w. s.f.R.l. is a powerful tool for spectroscopic applications.

Clean Surface

The adsorption of methanol on clean and oxygen-precovered Ag{111} has been investigated by high-resolution infrared spectroscopy. On the clean surface a highly inclined, associatively adsorbed methanol overlayer was detected. The presence of coadsorbed atomic oxygen results in the formation of a surface methoxy species, which is shown to have its C-O bond axis oriented normal to the surface by the application of the metal-surface selection rule.
