Prefaces are usually written when a manuscript is finished. Having finished this book I can
clearly see many shortcomings in it. But if I began to eliminate them I would probably write …

A rotational analog of the vibrational potential energy surface is introduced for describing the
rotational fine structure of polyatomic molecules. Classical trajectories on rotational energy …

A review is given of the physical phenomena observed when polyatomic molecules interact
with intense infrared radiation pulses. A brief historical account is given of earlier …

High-resolution infrared spectra have been remeasured for the ν 2, 2ν 2, and ν 4 bands of 4
NH 3 using a vacuum grating infrared spectrometer and a diode laser spectrometer. Far …

The possibility of initiating chemical reactions by high-intensity laser exci tation has captured
the imagination of chemists and physicists as well as of industrial scientists and the …

In this chapter we review excitation and dissociation experiments performed with pulsed
lasers at single infrared frequencies. The review treats five areas of this subject: data …

High‐resolution spectra of the infrared‐active stretching fundamental ν3 of 238UF6 have
been obtained between 620.6 and 633.5 cm− 1 using tunable semiconductor diode lasers …

The integrated infrared band intensities of the fundamental vibrational modes in SF6 have
been measured by the Wilson–Wells–Penner–Weber method. The results are 1361±34 km …

Infrared spectra from 32 to 3000 cm− 1 of SF 6 were recorded at several pressures, from
below atmospheric pressure up to 20 atm and in the liquid phase at temperatures from 228 …

The strongest portion of the 3ν 3 band of SF 6 has been recorded at T= 160 and 295 K with
Doppler-limited resolution using a tunable laser difference-frequency spectrometer. The …
