Abstract
The infrared spectra of the upsilon(3) and upsilon(9) bands of isotopically pure (CH2Cl2)-Cl-35 have been recorded at a resolution of 0.0025 cm(-1) in the range 600-800 cm(-1) with a Bruker IFS 120 HR Fourier Transform interferometer. The Coriolis coupling between the two CCl2 stretching fundamentals upsilon(3) and upsilon(9) has been investigated, An effective coupling constant xi(3,9)(c) = 0.20101(3) cm(-1) (zeta(3,9)(c) = 0.98) was obtained from a rotational analysis of spectra recorded at room temperature. From relative intensities the ratio of the vibrational transition moments of the fundamentals upsilon(3) and upsilon(9) could be estimated asI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
