フェノールのCH面外変角振動吸収に及ぼす水素結合の影響

抄録

Effect of hydrogen bond on the C-H out-of-plane vibration absorption in phenol was examined. It was found that such absorption transits to a higher frequency region when a proton acceptor is added to the carbon disulfide solution of phenol to form hydrogen bond between the two. The degree of such a shift was assumed to approximately correspond to the strength of hydrogen bonding between the two components. It was clarified that this effect of hydrogen bond should be considered apart from the solvent effect.
