摘要：

A tritium enhanced water absorption spectrum previously recorded in the 7200-7245 cm(-1) region is analysed. Variational calculations for HTO predict absorption to be dominated by the 2 nu(3) vibrational band in this region. New assignment are made for HTO based on this line list with a band origin measured to be at 7236.03 cm(-1). A calculated T2O line list predicts absorption in this region to be below the experimental detection limit despite the large quantity of tritium present. From 170 lines observed 37 known (H2O)-O-16 lines are identified and 111 new HTO assignments are made. (C) 2013 Elsevier Inc. All rights reserved.
