The infhrence of exchange interactions on molecular conformations is ihustrated by considering their role in stabilizing the gauche conformation of the npropylhalides. The conformational energy is c&Mated as a sum of exchange Interactions for ciusters of non-bonded atoms. The exchange component is e

IR spectra of 2-baloethanoI.s (CH2XCH20H, X = CI, Br, and I) in carbon disulfide were measured at 25°C up to 2.5 kbar. The volume changes accompanying the transformation to the Gg conformer of the compounds were -12, eO.5, and +1.3 cm3 moT' for X = Cl, Br, and I, respectively.
## Abstract Of the two known families of double‐stranded DNA conformations, A is stable in less‐polar, and __B__ in more‐polar solutions. In some water‐nonelectrolyte solutions, __B__ to __A__ transition occurs when water activity in the system is near 0.8. In such systems, however, as water‐methan
