“…From the 1960s, Herzberg and Monfils have studied its absorption spectrum over a wider range with a much higher accuracy, which led to the discovery of new electronic states (B . [11][12][13] In subsequent years Wilkinson, 14 Bredohl and Herzberg, 15 Dabrowski and Herzberg, 16 Takezawa and Tanaka, 17 and Larzillière et al 18 have further extended the spectral investigations using classical spectrometers. Later, after the development of nonlinear optical techniques, tunable extreme ultraviolet (XUV) radiation from a laser-based source was used to yield improved accuracy in the spectroscopy of the D 2 Lyman and Werner bands.…”

An extensive survey of the D 2 absorption spectrum has been performed with the high-resolution VUV Fourier-transform spectrometer employing synchrotron radiation. The frequency range of 90 000-119 000 cm electronic states correlate with the D(1s) + D(3 ) dissociation limit, but support a few vibrational levels below the second dissociation limit, respectively, v = 0-3 and v = 0-1, and are also included in the presented study. The complete set of resulting level energies is the most comprehensive and accurate data set for D 2 . The observations are compared with previous studies, both experimental and theoretical.

“…Consequently, precise and accurate measurements of the dissociation energy of the hydrogen molecule and its deuterated isotopomers have played an essential role in the validation of the theoretical results. To illustrate this point, we refer to the extensive work published during the past 50 years on the dissociation energy of HD, [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] which is the subject of this communication. Many more articles have been published on the dissociation energy of H 2 and D 2 ͑see Refs.…”

The adiabatic ionization energy [in units of hc, [Ei=124 568.485 81(36) cm−1] and the dissociation energy [D0=36 405.783 66(36) cm−1] of HD have been determined using a hybrid experimental-theoretical method. Experimentally, the wave numbers of the EF(v=0,N=0)→np[X+(v+=0 and 1, N+=0)] and EF(v=0,N=1)→np[X+(v+=0,N+=1)] transitions to singlet Rydberg states were measured by laser spectroscopy and used to validate predictions of the electron binding energies by multichannel quantum defect theory. Adding the transition energies, the electron binding energies and previously reported term energies of the EF state led to a determination of the adiabatic ionization energy of HD and of rovibrational energy spacings in HD+. Combining these measurements with highly accurate theoretical values of the ionization energies of the one-electron systems H, D, and HD+ further enabled a new determination of the dissociation energy of HD.

“…Comparing the generating expression for α(R) [9] in which Ελ', Ελ are BO eigenvalues of the electronic wave equation in λ' and λ electronic state, with (6) we see that a mass-dependence of Ελ may be a potential source of this peculiar property. Such an effect has been found, for example, for dissociation energy of 1 Η2 , 1 Η2 Η, and 2 Η2 [26] that is strictly related to eigenvalues Ελ.…”
