The infrared spectrum of sunspots is analyzed in the H-band region (5540-6997 cm 1) with the aid of a new, hot (T ¼ 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 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. Subject headings: infrared: solar system — infrared: stars — molecular data — sunspots On-line material: color figure, machine-readable tables
