Abstract

A theory of liquid water is developed by assuming that the molecules in the liquid state have solid-like and gas-like degrees of freedom. The spectroscopic data are used in assigning the vibrational frequencies of solid-like molecules. The calculated values of molar volume, vapor pressure, entropy, entropy of vaporization, expansion coefficient, compressibility, heat capacities at constant volume and at constant pressure, surface tension and critical point properties are all in excellent agreement with the observed data.

액체분자는 고체 및 기체와 같은 자유도를 갖는다는 가정하에 물에 관한 이론을 얻었다. 고체와 같은 분자의 진동수를 알아내는 데에 분광학적인 데이타를 이용하였다. 몰부피, 증기압, 엔트로피, 증발 엔트로피, 팽찰률, 압축률, 일정한 부피 및 일정한 압력하에서의 열용량, 표면장력, 임계점등을 계산한 결과 모두가 실험치와 아주 잘 일치하였다.
