Scientific paper

The infrared spectrum of a sunspot is analyzed in the L-band region 3.1-4.0 μm (2497-3195 cm-1) and 2.02-2.35 μm (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 newH216O 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.
