Notes

1A0 = -615.4. Small J-dependence Veseth, 1972.
2DeltaG(1/2) and alpha for the 3Pi0+ component only.
3Lambda-type doubling,Deltanuef(v=0) = +44.72 + 0.0056J(J+1).
4Lines are sharp for the 3Pi0+ state only. Line width increases in the order 3Pi0+ < 3Pi0- < 3Pi1 < 3Pi2, and also with increasing vibrational energy. The predissociation is due to interaction with the unstable 5Sigma- state arising from As(4S) + H(2S) Dixon and Lamberton, 1968.
5From the "true" B0 values in Veseth, 1972.
6Lambda-type doubling,Deltanuef(v=0) = +0.0214J(J+1).
7Spin splitting constants lambda0 = +58.87, gamma0 = -0.281.
8From the predissociation in A 3Pi.
9From a short extrapolation Dixon and Lamberton, 1968 of the 3Pi state to the limit As(2D) + H(2S).
10A0 = -616.9, small J-dependence Veseth, 1972; A1 = -599.8.
11Lambda-type doubling, Deltanuef(v=0) = +43.39 + 0.00472J(J+1).
12Lambda-type doubling, Deltanuef(v=0) = +0.0046J(J+1).
13Spin splitting constants lambda0 = +58.811, gamma0 = -0.l475.
14H0 = +5E-9.
