Farhataziz,

The absorption spectra induced in neat liquid ammonia and ammoniacal solution of N/sub 2/O by nanosecond pulse radiolysis have been measured for wavelength range 250 to 325 nm. The results indicate that the absorption spectrum induced in liquid ammonia is a composite of absorption spectra of e/sub am//sup -/ and NH/sub 2/. The absorptions due to e/sub am//sup -/ decrease with decreasing wavelength, and are attributed to the tail of the absorption spectrum (maximum absorption in near infrared) of e/sub am//sup -/. The absorption spectrum for NH/sub 2/ has a shoulder at approximately 255 nm. In liquid ammonia at 23/sup 0/C, the extinction coefficient for NH/sub 2/ at 250 nm is 1.1 x 10/sup 3/ M/sup -1/ cm/sup -1/.
