Absolute line intensity measurements of hot bands for carbonyl sulfide at 12 μm

Abstract

Using diode-laser spectroscopy, the intensities of 58 lines of the ν 1+ ν 2 1− ν 2 1 band and 36 lines of the 2 ν 1− ν 1 band of OCS have been measured. The corresponding band strengths S ν 0 and the vibrational transition dipoles μ ν have been derived through least squares fitting of these individual intensities. The band strengths values have been determined with a precision better than 2.5%.
