FIG. 1.

The X 3Δ1(v = 0) J = 1 ← J = 2 pure rotational spectra for 186W12C (bottom) and 184W12C (top) and associated energy levels. Both electric (e/fe/f) and magnetic dipole (e/ff/e) transitions are observed with comparable intensity because of the high microwave power (∼10 mW) and long interaction time (∼30 μs) achieved by using a seeded argon beam.

FIG. 2.

Field-free, high resolution, LIF spectra in the region of the R(2), Q(3), and P(4) lines of the [17.6]2X 3Δ1(1,0) band for 186W13C and associated energy levels. The three features have a common upper energy rotational terminus. The nearly identical splitting demonstrates that the magnetic hyperfine interaction in the X 3Δ1(v = 0) is negligible.
