Polarized Absorption Spectrum of Sodium Benzenesulfonate

Abstract

The polarized absorption spectrum of sodium benzenesulfonate in a stretched polymer film was measured at -170°c, and the polarization of each vibronic band in the ¹L_b transition was determined. It has been found that the short axis polarized vibronic bands of ¹L_b are observed at 37040 (ν=0), 37990 (ν=a₁), 38940 (ν=2a₁) and 39890 cm^-1(ν=3a₁) and the long axis ones at 37660 (ν=b₂), 38610 (ν=b₂+a₁), 39560 (ν=b₂+2a₁) and 40520 cm^-1(ν=b₂+3a₁).
