An experimental infrared spectrum due to Orphal and Ruth (2008) [10] recorded using isotopically enriched water in the 6000-7000 cm(-1) region is analysed and assigned. The assignment procedure is based on the use of known transition frequencies for (H2O)-O-16 and (H2O)-O-18, existing variational line lists for (HDO)-O-16 and (D2O)-O-16, and newly calculated variational line lists for (HDO)-O-18 and (D2O)-O-18. These new variational line lists are presented herein. The main absorption comes from (HDO)-O-16 and (HDO)-O-18, for which there are few previous assignments in the region. Assignments to 426 new (HDO)-O-18 lines are presented. In all 3254 of the 4768 lines observed in the spectrum are assigned, resulting in a number of newly determined energy levels. These assignments are in agreement with the recent work of Mikhailenko et al. (2012) [41].
