Abstract
The microwave spectrum of AsF3 is re‐examined under high resolution permitting the evaluation of small interactions due to centrifugal distortion and I·J effects, as well as a more precise determination of the rotational constant and quadrupole interaction. The constants determined are: B = 5878.971±0.002 Mc, (eqQ)As = −236.23±0.05 Mc, DJK = −9.±2. kc, a = −6.±7. kc, b = 6.±2. kc, α2 = −5.±1. Mc, and α4 = −0.16±0.04 Mc. In addition, the bond angle is estimated from the quadrupole interaction by means of a comparison with AsCl3, yielding ∠F–As–F = 102°±2°.
