摘要: Abstract The effect of temperature T ranging from 293 to 393 K on absorption and fluorescence spectra benzonitrile (BN) in ethyl acetate is studied. BN remain unchanged with increasing T. analysis band shift by the Bilot Kawski theory [L. Bilot, A. Kawski, Z. Naturforsch. 17a (1962) 621], for known dipole moment value ground state μg = 4.18 D α/a3 = 0.5 (α polarizability a Onsager interaction radius solute), yield average excited μe = 4.42 D. This satisfactory agreement 4.45, 4.51 4.57 D obtained previously Stark rotational lines.
