Abstract
Thea3Π-X1Σ+transition of AlF has been observed in absorption by heating a mixture of AlF3and Al powder to approximately 1 600 K in a King type furnace. The position of theQ2head of thea3Π-X1Σ+(0, 0) band is found to be 27 254.1 cm-1or 3 668.13 Å, which is in good agreement with the value of the singlet-triplet separation determined from earlier perturbation analysis. The (0, 0) and (1, 1) bands have been rotationally analyzed. The following equilibrium values of constants (in cm-1) have been determined for theastate:Te= 27 239.4 (1) ωe= 830.3 (3) ωexe= 4.6 (2)Be= 0.55718 (3) αe= 0.00468 (5)Keywords
