✦ Synopsis

Absolute line intensities and Herman-Wallis type intensity parameters of 12 C 16 O 2 are experimentally measured for the first time for the (40 0 1) IV R (00 0 0) band at 7460 cm 01 and the (40 0 1) I R (00 0 0) band at 7921 cm 01 . The rotationless band strengths at 296 K are respectively S 0 vib [IV] Å 0.0429(6) 1 10 022 cm 01 /(molecule/cm 2 ) and S 0 vib [I] Å 0.00189(6) 1 10 022 cm 01 /(molecule/cm 2 ).

In addition, previous measurements on the (40 0 1) II R (00 0 0) and (40 0 1) III R (00 0 0) bands have been reanalyzed to be consistent with definitions of Herman-Wallis parameters currently in use.

The absolute rotationless transition moment squared for the This value is about 8.6% smaller than the value assumed for HITRAN 2000. The measured Herman-Wallis intensity factor of this band is F = 1 + 0.01168(11) m + 0.0001065(79) m 2 . The determination of self-broadening coefficients is improved
