| Abstract: | Emission spectra of BH(A
1Π-X
1Σ+) system were recorded and studied using a low pressure (3.0 torr) arc in flowing hydrogen and argon + hydrogen mixture. The
rotational distributions in theA
1Π state determined from the intensities of rotational lines for the 0–0 band of theA-X system conforms to a Maxwellian distribution with effective rotational temperature of 1000 ± 50°K. Intensities of Balmer
lines of hydrogen were measured and used to determine electronic excitation temperature which was found to be around 2000°K. |
