Triatomic Linear Molecules Containing Carbon and Oxygen, Sulfur, Selenium, or Tellurium. III. Absolute Intensity of the sgr;3Band of CSe2

摘要

The rate of change of the axial dipole moment with asymmetric bond extension in carbon diselenide has been computed from the measured gas phase infrared absorption intensity of the sgr;3fundamental band. The absolute intensity was measured by the pressurehyphen;broadening technique, using nitrogen or air as the foreign gas. The magnitudes ofdmgr;/drfor CO2, OCS, CS2, and CSe2are compared. Also, the absorption intensity of the sgr;3band of CSe2dissolved in CS2was measured.
