Optical properties of water in the near infrared
- J Opt Soc Am, 64(8), p.1107-1110, 1974 .
The real n (v)and imaginary k (v)parts of the complex refractive index of water at 27 degree C have been determined from measurements of spectral reflectance at near-normal incidence and from measurements of the transmittance of water in carefully constructed absorption cells. Values of n (v)are reported in graphical and tabular form for the spectral region 3800-27 800 cm** minus **1; values of the Lambert absorption coefficient a(v)are presented graphically and in tabular form, along with k(v)for the region 3800-14 500 cm** minus **1. Upper limits of k(v)are established for the region 14 500-27 800 cm** minus **1. The results are compared with earlier studies.
