The conformational changes in isobutyl halides (<I>i</I>-BuX) and <I>s</I>-butyl halides (<I>s</I>-BuX) in hexane and methanol have been analyzed by Raman spectroscopy as a function of temperature and pressure. The enthalpy and volume differences in the conformational changes from P<SUB>C</SUB> (<I>trans</I>) to P<SUB>H</SUB> (<I>gauche</I>) of <I>i</I>-BuX and from S<SUB>HH</SUB>(<I>trans</I>) to S<SUB>HH′</SUB>(<I>gauche</I> I) and to S<SUB>CH</SUB>(<I>gauche</I> II) of <I>s</I>-BuX in the dissolved state have been obtained. The enthalpy and volume differences, Δ<I>H</I> and Δ<I>V</I>, of all the conformational changes depended on the solvents and the concentration in solution. In the solution of hexane, the Δ<I>H</I> (P<SUB>C</SUB>→P<SUB>H</SUB>) of <I>i</I>-BuCl and <I>i</I>-BuBr both increased with a decrease in the concentration of <I>i</I>-BuX. The Δ<I>V</I> (P<SUB>C</SUB>→P<SUB>H</SUB>) of <I>i</I>-BuCl increased with an increase in the contents of the solvents, hexane, but that of <I>i</I>-BuBr decreased. The concentration dependences of Δ<I>H</I> and Δ<I>V</I> were discussed on the basis of the intermolecular interactions. The relation between Δ<I>H</I> and Δ<I>V</I> was also discussed on the basis of thermodynamic consideration.
