Notes

1Two strong bands between 104000 and 116000 cm-1, not yet analysed.
2Absorption bands above 100000 cm-1, not yet analysed.
3The vibrational and rotational constants, were obtained from a fit to the seven lowest vibrational levels di Londardo and Douglas, 1973. See 7.
4RKR potential curves Fallon, Vanderslice, et al., 1960, di Londardo and Douglas, 1973.
5-0.000950(v+1/2)2 + 0.000060l(v+1/2)3; see 3.
6+0.182E-4(v+1/2) + 0.00551E-4(v+1/2)2; see 3.
7Very extensive band system (also called V-X) extending in absorption from 96000 to 117000, in emission from 36000 to 70000 cm-1. Strong perturbations above v'=27, but bands have been identified to v'=73. The B (or V) state was also observed in the electron energy loss spectrum Salama and Hasted, 1976.
8HF is quite transparent to 1650 Safari, 1954. Theoretical potential curves for three repulsive states (3Π, 1Π, 3Σ+) arising from ground state atomic products were given by Dunning, 1976.
9Introduction of the Dunham correction Webb and Rao, 1968 gives ωe = 4138.767 Webb and Rao, 1968 and Be = 20.9561.
10+0.90(v+1/2)3 - 0.0ll0(v+1/2)4 - 0.00067(v+1/2)5, v≤9 Webb and Rao, 1968. A different formula for higher vibrational levels (v≤19) was derived by Johns and Barrow, 1959. All levels up to the last (v=19) are tabulated in di Londardo and Douglas, 1973).
11For v=14,...19 the rotational levels break off at decreasing J on account of predissociation by rotation. A few broadened lines near these limits have been observed di Londardo and Douglas, 1973. From the limiting curve the dissociation energy 47333 ± 60 cm-1 has been determined di Londardo and Douglas, 1973.

21From photoelectron spectra Walker, Dehmer, et al., 1973, Guyon, Spohr, et al., 1976. Earlier photoionization studies yielded 16.007 eV Berkowitz, Chupka, et al., 1971, a value strongly affected by the presence of autoionizing Rydberg levels in the threshold region Guyon, Spohr, et al., 1976. The second ionization potential (removal of a 3σ electron) from the photoelectron spectrum Berkowitz, 1971, Guyon, Spohr, et al., 1976 is 19.118 eV in agreement with the value derived from the spectrum of HF+. The third and fourth ionization potentials (removal of a 2σ and 1σ electron, respectively) are 39.61 Banna and Shirley, 1975, Shaw and Thomas, 1975 and 694.25 eV Shaw and Thomas, 1975; these are vertical potentials from X-ray photoelectron spectra.
221-0, 2-0 bands studied in absorption under high resolution by Herget, Deeds, et al., 1962, Webb and Rao, 1968, 3-0, 4-0, 5-0 in the photographic infrared by Naude and Verleger, 1950, Fishburne and Rao, 1966. In emission, rotation-vibration bands have been studied by Mann, Thrush, et al., 1961 and Sileo and Cool, 1976, the latter extending the chemical laser emission, first observed in the 2-1 band by Kompa and Pimentel, 1967, to v=9 and Δv=6. Electric discharge induced laser emission in the 3-2, 2-1, 1-0 bands, see Deutsch, 1967, 2, Coldhar, Osgood, et al., 1971.
23Line strengths, collision-broadened widths, dipole moment function Meredith, 1972, Spellicy, Meredith, et al., 1972, Lie, 1974, Rimpel, 1974, Sileo and Cool, 1976, Yardley and Balint-Kurti, 1976. The radiative lifetime of v=1 [P(4) line] is 6.16 ms Hinchen, 1974. Sileo and Cool, 1976 give a vibrational dipole moment matrix for v ≤ 9 based on intensity measurements in chemical laser emission.
