Quantitative determination of the (2,0) band of deuterium in the near infrared via off-axis ICOS

Near-infrared off-axis integrated cavity output spectroscopy (oa-ICOS) was used to study the S(0)-S(3) transitions of the (2,0) vibrational band of deuterium from 6000 to 6350 cm−1. The transition frequencies, line strengths, pressure shifts, and effects due to pressure narrowing were quantified.
