The 2100-cm-1 bands of various isotopes of HCN have been measured with a resolution of about 0.01 cm-1 using the Fourier transform spectrometer constructed by J. Brault and co-workers at the National Solar Observatory. The frequencies of 500 HCN lines obtained from absorption spectra of three different isotopic species are reported with an accuracy of approximately 0.0001 cm-1. Six bands of HCN, two bands of H13CN, and two bands of HC15N were measured. The 001 ← 000 and 0310 ← 000 of H13CN were reported for the first time. New measurements of 0330 ← 000 forbidden transitions (Δl = 3) were made.
