Observation and analysis of fundamental bending mode of T2O

Abstract The absorption spectrum of the ν 2 band of T 2 O vapor has been observed at 0.04 cm −1 resolution. A total of 549 transitions has been assigned; 474 of these have been used to evaluate the rotational constants A , B , and C as well as the fourth-order and sixth-order distortion constants and one eighth-order constant for the upper vibrational state.
