NAME: ammonia
AUTHOR(YEAR): Watanabe(1954)
T: 298K
λ: 162.5-218.0nm

COMMENTS: Absorption measurements using a vacuum monochromator at a resolution of about 0.1 nm and a hydrogen discharge tube as a light source

Absorption coefficicients k (atm, 273K)-1 cm-1 plotted in Fig. 7 have been digitized and converted to 3.72×10-20)
