34Absolute intensities have been measured by Chamberlain and Gebbie, 1965.
35For observations and measurements of pressure-induced bands and pure rotation lines (DeltaJ=2) see Atwood, Vu, et al., 1967, Weiss and Cole, 1967. The pressure broadening of the lines has been studied by Babrov, 1964, Pourcin, Bachet, et al., 1967.

37The following constants (as well as corresponding values for H79Br) are given in Dabbousi, Meerts, et al., 1973: -muel(v=0,J=1) = 0.8265 D [in a later paper van Dijk and Dymanus, 1974 derive 0.8282 D from Stark effect of rotation spectrum]; -quadrupole and other hyperfine coupling constants; -gJ = 0.3712. These constants supersede earlier values of Schurin and Rollefson, 1957, Jones and Gordy, 1964, Tokuhiro, 1967, Van Dijk and Dymanus, 1969, van Dijk and Dymanus, 1970.

42In absorption the 1-0, 2-0, 3-0, 3-1, 4-0, 5-0, 6-0 bands have been studied Naude and Verleger, 1950, Thompson, Williams, et al., 1952, Plyler, 1960, Rank, Fink, et al., 1965, Bernage, Niay, et al., 1973; in emission 1-0, 2-1, 3-2, 4-3 Mould, Price, et al., 1960, James and Thibault, 1965. The constants in the table are from Rank, Fink, et al., 1965, those of James and Thibault, 1965, Bernage, Niay, et al., 1973 are very similar and of comparable accuracy. See also Ogilvie and Koo, 1976. Absolute intensities have been measured Babrov, 1964, Babrov, Shabott, et al., 1965, Rao and Lindquist, 1968, Gustafson and Rao, 1970 and the dipole moment function has been calculated; Urquhart, Clark, et al., 1972 give for H79Br[D, ]: muel(r) = +0.788 + 0.315(r-re) + 0.575(r-re)2; see also Jacobi, 1967, Tipping and Herman, 1970, Rao, 1971.
