Abstract
Near-IR distributed feedback semiconductor laser spectroscopy of HCN in natural abundance and in an H13CN-enriched sample has been performed from 6380 to 6410 cm-1. Absolute accuracy of wavenumber measurement was 0.0005 cm-1 using the 3-0 band of CO as a reference. New sets of molecular constants for the (2 00 0)-(0 00 0) and (21 0)-(011 0) bands of H12C14N and H13C14N have been determined by combining the present results together with the existing data. Two tables of the calculated wavenumbers are given for calibration standards in the 1.5-μm region.
