    3100A Band System of Water
    (Savannah State College (Savannah State University), 1970-12) Chandra, Kailash
    Although an exact calculation of the energy of the lowest triplet state of H2O is lacking, previous theoretical approximations by Niira (1) and Laidler (2) predicted the lowest state ofHOto lie below the first singlet state. A semiempirical estimate (3) of the smglet-triplet transition energy can be inferred from the work of La Paglia (4) to be 'v 3.8 ev. The importance of this triplet state in the radiation chemistry of water was discussed at the National Research Council's conference (5) on Basic Mechanisms in Radiobiology. Since that time at least three researchers in electron Physics, (Schulz (6), Raff (7), and Compton (3, 8) ) have reported a broad inelastic loss process for electron in water vapour with an onset between 3.5 and 4.4 e.v. Larzul (9) and co-workers utilized a new differential absorption technique and detected a broad absorption in water between 2600 and 3000A. Henriksen (10) reported a few emission bands in the region 3090-3022A for a mixture of CO and Argon gas which proved to be elusive and did not appear following every filling of the discharge tube under identical conditions each time. It was suspected that these bands were due to an impurity of water vapour. Stickler and Arakawa (1 1) observed similar bands from Argon, at pressures of the order of 1 atm, excited by a particles and associated them with the presence of water vapor. Brocklehurst (12) also found two band heads in an emission of Argon excited by X-rays at 3078 and 3088 *5A but he identified them as the Q-heads of the 3064 band (the 0,0 band of 2G^27r transition) of OH molecule. We have observed (13) about fifteen bands in the region 3090-3020A from an excitation of a mixture of H2O, CeFg and Xenon. These bands, which were observed each time following every filling of the discharge tube, are analysed and the results are reported in this paper.
