액체 내에는 분자들 주위ㅔ 분자크기의 빈자리가 들어 있게 되어 빈자리로 뛰어들면서 기체와 같은 자유도를 갖는 분자와, 빈자리에서 좀 떨어져서 고체와 같은 자유도를 같는 분자와, 빈자리 때문에 변형에너지를 받고서 천이상태에 있는 분자들이 있다고 가정하여 액체에 대한 상태함을 유도하여 알곤, 질소, 벤젠, 클로로포름 및 이황화탄소의 액체상태에서의 열역학적 성질들을 계산한 결과 실측치와의 좋은 일치를 얻었다.

In formulating the Transient State Theory of Significant Liquid Structure it is assumed that there exist holes of molecular size in liquids and that the liquid state is partitioned in three states, namely, solid-like state, representing the molecules apart from holes; gas-like state, representing the molecules jumping into the holes; and the transient state, representing the molecules in a possible state of jumping into the holes by aquiring the strain energy due to the holes. It is found that the partition function derived according to the proposed theory can be applied to the liquids of argon, nitrogen, benzene, chloroform, and carbon disulfide with good accuracy.
