5.3.4 Absorption

Ultraviolet Absorption of Pure Liquids:

The following tables present data on the UV absorption edge of several common liquids. The data were obtained using a 1.00–cm pathlength cell and a water reference. From Bruno, T. J. and Svoronos, P. D. N., CRC Handbook of Basic Tables for Chemical Analysis (CRC Press, Boca Raton, FL, 1989), p. 213.

* Transmission limits are the wavelengths of the last visible blackening on a spectrogram for reasonable exposure and development time. From Klevens, H. B. and Platt, J. R., Ultraviolet transmission limits of some liquids and solids, J. Am. Chem. Soc. 69, 3055 (1947).

Spectral transmission ranges of several fluids used for liquid filters. The end points are for 50% transmission through 1 mm of the liquid [from Cook, L. M. and Stokowski, S. E., Filter materials, in Handbook of Laser Science and Technology, Volume IV: Optical Materials, Part 2 (CRC Press, Boca Raton, 1995), p. 151].

For other organic and inorganic filter solutions, see Pellicori, S. F., Transmittances of some optical materials for use between 1900 and 3400 Α, Appl. Opt. 3, 361 (1964); Bass, A. M., Short wavelength cut–off filters for the ultraviolet, J. Opt. Soc. Am. 38, 977 (1948); Ingersoll, K. A., Liquid filters for the visible and near infrared, Appl. Opt. 10, 2473 (1971); Ingersoll, K. A., Liquid filters for the ultraviolet, visible, and near infrared, Appl. Opt. 11, 2781 (1972).
