Ultra-Violet Absorption and Raman Effect for Hydrazine


THE ultra-violet absorption in hydrazine vapour, N2H4 (saturation pressure over the liquid at room temperature), consists of five or six nearly equidistant intensity maxima at about 2326, 2320, 2276, 2250, 2225 A., followed by continuous absorption, beginning at about 2200 A. and extending into the whole quartz region.1 The band absorptions are entirely devoid of rotation structures at 5.4 A. per mm. dispersion.
