Stabilized Tunable Diode Laser Measurements of the P(2) Line in the (13)CO Fundamental Band Broadened by Helium at Temperatures between 11.5 and 298.6 K.
We determined accurate He-broadening parameters and collisional cross sections for the P(2) line in the fundamental band of CO at room temperature and at intermediate temperatures down to 11.5 K. We also determined a precise value for the temperature dependence of the line-broadening parameter on (T)(-n) with n equal to 0.548+/-0.010. Our results validate the microwave results for the J=1 to J=2 rotational transitions measured over the same range of temperatures which were reported previously by Beaky et al. (1996, J. Chem. Phys. 105, 3994-4004). Copyright 2001 Academic Press.
