Circular dichroism properties of some forbidden lines of propylene oxide (sub)millimeter transitions.

Transition	v₀ (GHz)	A_ji (s⁻¹)	g_Kuhn
2_{2 0} → 2_{0 2}	46896.200	1.402 × 10⁻¹⁴	5.708
3_{2 1} → 3_{0 3}	47168.500	3.542 × 10⁻¹⁴	5.697
4_{3 1} → 4_{1 3}	90187.900	5.972 × 10⁻¹³	3.039

Notes. Only the line center frequency is reported, but it should be noted that the two symmetry species of each line, A and E, are slightly displaced from each other. The Einstein A coefficient, A_ji, is reported for each line, as is the Kuhn dissymmetry factor, g_Kuhn.
