Raman Apparatus Using Laser Excitation and Polarization Measurements. Rotational Spectrum of Fluorine

Volume 23, Number 1 (Feb. 1969) Page 8-12

Claassen, Howard H.; Selig, Henry; Shamir, Jacob


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 B0=0.8841±0.0006 cm−1, corresponding to r0=1.4168±0.0005 Å.
