Notes

1Broad diffuse peaks, principal peak at 48440 cm-1. 3
2Repulsive state with rather flat potential function.
3In emission from low-pressure (0.5 - 5 torr) reactions of metastable Kr atoms with Br2 or CH2Br2, Cl2 or CCl4 Golde, 1975. The KrCl bands were also observed in electron-beam- excited mixtures of Ar and Kr + Cl2 Murray and Powell, 1976. The upper states are ionic states arising from Kr+ + Br- or Cl- although the adiabatic dissociation products are Kr(3P2) + Br or Cl; the dissociation energies can be estimated as 3.93 eV for KrBr and 4.33 eV for KrCl and are very similar to those of the ground states of RbBr and RbCl.
