Vibration-rotation bands of isotopic carbon disulfide at 4.6 μm

The 1001-0000 bands of 12C34S2 and 13C34S2 have been measured with a resolution of 0.03 cm−1. The following “hot” bands associated with this transition were also measured and analyzed: 1111-0110, 2001–1000 for both isotopic forms. For 12C34S2, the Δ-Δ transition 1221–0220 has also been observed. In addition, the 1001-0000 bands of the isotopic species 12C32S34S and 12C33S34S were measured.
