A high resolution FTIR (apodized instrumental bandwidth 0.004 cm(-1) FWHM) spectrum has been measured for the isotopically pure benzene molecule (C6H6)-C-13 in the range 600-850 cm(-1). Accurate molecular constants have been obtained for the fundamental vibration nu(11) (Wilson's notation, which is used here: nu(4) according to Herzberg's notation) of (C6H6)-C-13 with band center at 672.12930(5) cm(-1). Several hot-bands have been analyzed as well. Improved ground state constants have been deduced from a fit of ground state combination differences.

Abstract
A high resolution FTIR (apodized instrumental bandwidth 0.004 cm(-1) FWHM) spectrum has been measured for the isotopically pure benzene molecule (C6H6)-C-13 in the range 600-850 cm(-1). Accurate molecular constants have been obtained for the fundamental vibration nu(11) (Wilson's notation, which is used here: nu(4) according to Herzberg's notation) of (C6H6)-C-13 with band center at 672.12930(5) cm(-1). Several hot-bands have been analyzed as well. Improved ground state constants have been deduced from a fit of ground state combination differences.File in questo prodotto:
