Abstract
The molecular absorption spectra of pH dyes, employed for ammonia sensing are investigated. Differences of absorption spectra of Bromothymol Blue and Bromocresol Purple dyes, dissolved in water and entrapped in Polymethylphenylsiloxane film are discussed. Correspondence of dye-films absorption bands shape to the Gauss distribution shape in the spectral region of light source emission band was determined.
