Abstract
The infrared spectrum of sunspots is analyzed in the H-band region (5540-6997 cm(-1)) with the aid of a new, hot (T = 1800 K) laboratory emission spectrum of water covering 4878-7552 cm(-1). There are 682 lines in the sunspot spectrum and 5589 lines in the laboratory spectrum assigned quantum numbers corresponding to transitions due to (H2O)-O-16 using a combination of previously known experimental energy levels for water and variational line lists. A further 201 unassigned lines common to both spectra can also be associated with water.
