Abstract

The infrared spectrum of sunspots is analyzed in the H-band region (55406997 cm-1) with the aid of a new, hot (T = 1800 K) laboratory emission spectrum of water covering 48787552 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 H216O 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.
