Comments: Broadband vibrational spectra acquired at 298 ± 2 K and 228 ± 5 K, as well as high-resolution 
rotational spectra of the A <-- X 7,0 and 12,0 vibrational bands are presented. Wavenumber positions for the 
spectra are obtained with high accuracy, and cross section assignments are made, incorporating the existing 
literature. With 35 cm-1 (0.40 nm) resolution the absolute cross section at the peak of the 7,0 band is determined 
to be (1.58 ± 0.12) × 10-17 cm2 molecule-1 at 298 ± 2 K and (1.97 ± 0.15) × 10-17 cm2 molecule-1 at 228 ± 5 K.
