The rotational structure of the ν1 band of D14N3 in the wavenumber region 2200-2600 cm-1 has been measured by means of Raman spectroscopy with a resolution of 0.3 cm-1. Both components of the hybrid band were observed. In addition, an infrared spectrum of the same wavenumber region was recorded with a resolution of 0.07 cm-1. In the infrared experiment mainly the parallel component was observed. The molecular parameters determined from the observed wavenumbers in the Raman spectrum are (ν0)1=2478.32 (1) cm-1, A1 = -11.096 (1) cm-1,½(B1 + C1)=0.37187 (4) cm-1, (DK)1 = 2.85 (2) × 10-3cm-1 and (HK)0 = 2.7 (4) × 10-6 cm-1. From the infrared spectrum the following values were obtained: (ν0)1 = 2478.451 (3) cm-1, A1 = 11.0902 (4) cm-1, B1 = 0.378186 (9) cm-1, C1 = 0.365032 (9) cm-1, (DK)1 = 2.69 (2) × 10-3 cm-1 in addition to values for (D1)1 and (DJK)1. The discrepancy between the values for (ν0)1 obtained from the two experiments is mainly due to uncertainties in the absolute calibration and to differences in the intensity distributions of the unresolved Q-branch lines in the two types of experiments.
