The present subvolume provides evaluated data from HD16O, HT16O, HD17O, HD18O, and DT16O isotopologues. The introduction is intended to give a quicker access to the meanings of symbols found in the data tables. It reports molecular theories and equations, based on which most of the evaluated data given in the tables are established. These tables are preceded by an additional index in order to facilitate the search for specific information.

The tables report molecular constants and/or, below about 5000 cm–1, assigned experimental line positions, intensities, and shape related parameters. Vibrational band origins and vibrational band intensities are also provided with no spectral range limitation. Additional information (list of symbols with their definitions, units, table of conversion factors, notations for the bands and energy levels, tables of energy-related units, selected fundamental constants,…) are also given. The subvolume ends with a reference section.
