Notes
| 1 | First members of two Rydberg series converging to the Li is ionization limit of LiCl at ~66eV (532300 cm-1); vibrational numbering not established. |

| 3 | Absorption cross sections Davidovits and Brodhead, 1967. |
| 4 | Diffuse absorption bands at 35642, 35032, 34482 cm-1. |
| 5 | Calculated Pearson and Gordy, 1969 from the rotational constants by use of Dunham's theory. From the infrared spectrum of the isotopic mixture Klemperer, Norris, et al., 1960 obtain we = 641.1, wexe = 4.2. For 6Li35Cl Moran and Trischka, 1961 find we ~ 705 by the molecular beam electric resonance method. |
| 6 | From the effective Be. Using the data of Pearson and Gordy, 1969 for the four LiCl isotopes Watson, 1973 has determined re at the minimum of the Born-Oppenheimer potential as 2.020700 . |
| 7 | Rot.-vibr. Sp. 10 |
| 8 | Nuclear reorientation spectrum of Li Kusch, 1949, Logan, Cote, et al., 1952, Kusch, 1959. |
| 9 | Thermochemical value Brewer and Brackett, 1961, Bulewicz, Phillips, et al., 1961, Hildenbrand, Hall, et al., 1964. A slightly higher value was suggested by Gurvich and Veits, 1958. |

| 11 | Electric dipole moment of 6Li35Cl: μel[D] = 7.0853 + 0.0868(v+1/2) + 0.00056(v+1/2)2 Hebert, Lovas, et al., 1968, see also Marple and Trischka, 1956,134. For electric quadrupole and other hyperfine coupling constants see Marple and Trischka, 1956, Gallagher, Hilborn, et al., 1972. The Zeeman spectrum was also studied by the molecular beam electric resonance method Freeman, Johnson, et al., 1974; gJ(7Li35Cl) = +0.10042 and +0.10064 μN for v=0 and 1, respectively, superseding an earlier value by the magnetic resonance method Mehran, Brooks, et al., 1966. |
| 12 | From D00(LiCl) and the electron affinities of LiCl and Cl. |
| 13 | From the photoelectron spectrum of LiCl- Carlstein, Peterson, et al., 1976; I.P. is reasonably close to the calculated electron affinity of LiCl [0.54 eV Jordan and Luken, 1976]; see also Jordan, 1976. |
| 14 | The relative intensities of the photoelectron peaks have been compared Carlstein, Peterson, et al., 1976 with calculated Franck-Condon factors. |
