Comments: For the (7, 0) vibrational band at 29 540 cm-1 (338.5 nm), the peak absorption cross-sections were determined 
to be 2.19±0.23 at 298 K, 2.23±0.23 at 273 K, 2.52±0.26 at 243 K, 2.75±0.29 at 223 K, and 3.03±0.31 at 203 K (all in 
units ×10-17 cm2 per molecule, at a spectral resolution of 3.8 cm-1, with error intervals of 2sigma).
