HIGH-RESOLUTION STUDY OF THE INFRARED BAND NU(2) OF (CHCL3)-CL-35

The Fourier transform spectrum of the nu(2) band around 676 cm(-1) of isotopically pure (CHCl3)-Cl-35 has been measured. The experimental re solution was near 0.0010 cm(-1). In this parallel band more than 3000 rotational lines, with J(max) = 100 and K-max = 56, were assigned. In the analysis a model for an unperturbed symmetric top band was applied . The fit of 2852 lines, with a standard deviation of 0.17 x 10(-3) cm (-1), led, among others, to the following results: nu(0) = 676.643310( 9) cm(-1), B-2 - B-0 = - 0.493903(6) x 10(-3) cm(-1) and C-2 - C-0 = - 0.109899(22) x 10(-3) cm(-1).
