Abstract
The infrared spectrum of a sunspot is analyzed in the L-band region 3.1-4.0 mu m (2497-3195 cm(-1)) and 2.02-2.35 mu m (4251-4962 cm(-1)) in the K band. A new laboratory emission spectrum covering 2500-6000 cm(-1) is analyzed to help make the assignments. Quantum number assignments are made using linelists computed using variational calculations, assisted by tabulations of experimental energy levels. There are 1207 new (H2O)-O-16 lines assigned in the L band and 508 new lines in the K band. Vibrational band origins of 11242.8 +/- 0.1 cm(-1) and 12586 +/- 1 cm(-1) are obtained for the (051) and (061) states.
