DATA OF:			
Zolotarev V. M., Demin A. V. 1977. Optical constants of water over a broad range of wavelengths, 0.1 Å-1 m. Opt. Spectr. 43, 157-161.			
			
			

NOTES:			
m' - real part of the refractive index (m = m' - im") relative to that of vacuum			
m" - imaginary part of the refractive index (m = m' - im") relative to that of vacuum

These values were obtained by the data authors for the following conditions:
water - unknown purity
temperature -  25°C
method - external reflection and attenuated total reflectance (ATR). The complex refractive index was calculated by the data authors by using the Fresnel and Kramers-Kronig analysis.
The absorption coefficient has been calculated by Jonasz M. (column CALC) from the imaginary part, m", of the refractive index by using the following formula: a(lambda) = 4 PI m"(lambda) / lambda, where lambda is the wavelength of light.			
			
			

Underscore (_) marks the absence of or incomplete data			
Each column is separated by a TAB - when you import the file into a spreadsheet all column headings should be aligned with the numbers.
