| Abstract: | The line intensities are calculated at temperatures of 263 K and 3500 K for the H2O band 201 at 0.94  m. The possibility of detecting these lines in sunspots is discussed. The amount of H2O is estimated to be 4.2 × 1020 molecules or 0.013 g cm–2 above optical depth equal to unity. However, other bands at longer wavelengths are more favourable for detection of H2O. |
