文摘

The ν7 band of cis-C2H2D2 was recorded in the 720–990 cm−1 region at 0.00096 cm−1 resolution. Rovibrational constants up to four sextic terms and band center of the ν7 band were improved by fitting 2823 infrared transitions. Ground state rovibrational constants of cis-C2H2D2 were derived accurately from a fit of 2634 GSCDs from this work.
