Classification laser spectroscopy

Absorption.—The studies reported here are conventional one-photon absorption studies on ground-state molecules and atoms. The use of a rapidly tuneable CW dye laser for direct absorption spectroscopy has been described.98 Transition probabilities in the spectra of Ne (I),97 and the classification of the 650.4 nm line of Xe97 have been discussed. Pressure-broadening coefficients for the atomic iodine 2P4-2Pj transition for C02, N2, He, Ne, Ar, Kr, and Xe have been measured as 7.4 0.7, 6.2 0.8, 3.6 0.3, 4.3 0.4, 5.1 0.5, 4.4 0.4, and 3.0 0.3, respectively.98 Measurements of the polarizabilities of alkali-metal atoms have been described,99 and hyperfine interactions in the excited states of sodium discussed.100 Excitation parameters in the vacuum-u.v. region... 

A classification scheme for laser-microwave spectroscopy based on well-defined three-step processes is displayed in Figure 5. It illustrates the great variety of possible experimental methods. The steps can be carried out in many different ways depending, for example, on the physical properties of the species under study. To be more specific, details of the three steps are as follows ...
