Spectra of heavy water have been obtained under high resolution between 1.25—4.1μ (2400—8000 cm—1). Approximately 4500 lines have been measured, and the majority of them analyzed into ten bands of D2O and nine bands of HDO. The analysis is described in some detail, spectra of all bands are shown and a partial table of lines and a complete table of energy levels are presented. The vibration-rotation constants are derived and compared with those of H2O.
The m easu red values of the wa velen gths of 60 lines in t he 1.1-to 2.3-micron spectral r egion are reported. T he a bsorpt ion lines of the ba nd s of .m ethane and w~ter vapor were used in the calibration. T he m ethods of measurement are disc ussed . Also d Iscussed a re the m ethods of superi mposing t he well-known em.ission lines of se.ver al sources on t he ~bsorpt ion lines tha t were meas ured. T he values obtained for some hnes are compa red with values reported by other workers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
