Abstract
Abstract Absorption spectra of 2-Fluoro-4-Bromo, 4-Fluoro-2-Bromo and 2-Fluoro-5-Bromo Toluenes have been investigated in the near ultraviolet region in vapour phase. The band systems correspond to allowed transitions with the most intense bands at 2742.09 A (36458 cm−1), 2745.96 A (36406 cm−1) and 2771.74 A (36068 cm−1) identified as 0,0 transitions in 2-Fluoro-4-Bromo, 4-Fluoro-2-Bromo and 2-Fluoro-5-Bromo Toluenes respectively. The bands in 4-Fluoro-2-Bromo Toluene have been analysed in terms of the ground state fundamental 208 cm−1 and excited state fundamentals 244, 611, 855 and 1211 cm−1 and the bands in 2-Fluoro-4-Bromo and 2-Fluoro-5-Bromo Toluenes are explained in terms of the upper state fundamentals 716, 987 and 1230 cm−1 and 722, 886 and 2130 cm−1 respectively.
