| The T, /7-Dependence of the Chemical Shift of the Hydroxyl Protons in Deeply Supercooled Methanol and Water  | | | | Abstract
| The hydroxyl proton chemical shifts 6 (H-O) of supercooled methanol (7" min = 149 K) and water have been determined (7" min = 183 K), and the pressure dependence of these shifts was measured up to 200 MPa. In both compounds the downfield shift of <5 (H-O) continues down to the lowest tempera-tures reached. This result disagrees with the two state models for the hydrogen bond formation in both liquids. The isotherms ö (H 2 0) show for T< 273 K an upfield shift that becomes more pronounced with decreasing temperature. For 6 (H-O-CH^), increasingp causes at all temperatures a downshift. | | | |
