Notes
1 | Two strong bands between 104000 and 116000 cm-1, not yet analysed. |
2 | Absorption bands above 100000 cm-1, not yet analysed. |
3 | The vibrational and rotational constants, were obtained from a fit to the seven lowest vibrational levels di Londardo and Douglas, 1973. See 7. |
4 | RKR 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. |
7 | Very 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. |
8 | HF 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. |
9 | Introduction 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). |
11 | For 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. |
12 | RKR potential curves Fallon, Vanderslice, et al., 1960, di Londardo and Douglas, 1973, Dunham potential coefficients Webb and Rao, 1968, Ogilvie and Koo, 1976.

21 | From 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. |
22 | 1-0, 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. |
23 | Line 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. |
