Abstract

Various schemes are compared for measuring depolarization factors in Raman spectra with laser excitation. Optical systems are discussed for producing a laser beam free of unwanted emission lines and for focusing scattered light on the slit and on the detector. The rotational spectrum of gaseous F₂ has been used to determine a rotational constant of <i>B</i>₀=0.8841±0.0006 cm⁻¹, corresponding to <i>r</i>₀=1.4168±0.0005 Å.
