Implication

Randomized trial determines optical constants of water, suggesting enhanced understanding of its properties.

Key Points

  • The aim is to determine the optical constants of water across a broad wavelength spectrum.
  • Extinction coefficients k(lambda) were calculated for water at 25 degrees C by smoothing spectral data.
  • Absorption bands were postulated for missing data in the vacuum ultraviolet to soft x-ray regions.
  • A Kramers-Kronig analysis was performed to derive the index of refraction n(lambda) from the smoothed extinction coefficients.
  • Extinction coefficients were successfully obtained and smoothed across the wavelengths from 200 nm to 200 μm.
  • Postulated absorption bands provided insights into the optical behavior of water where direct data were lacking.
  • The Kramers-Kronig analysis yielded a comprehensive index of refraction for the specified wavelength range.
