摘要: 本文把计算隔两个化学键的偶合常数2J的原理和方法,推广到烃类分子中的隔三个化学键的偶合常数3J和远程偶合常数4J5J……的计算。对20个化合物的57个偶合常数的计算结果表明,除了个别与实验值相差较大外,一般都能较好地符合。

Abstract: The principle and method for calculating geminal coupling constants 2J has been extended to the calculation of three bonds coupling constants 3J and long range coupling constants 4J,5J……in hydrocarbon molecules. The calculated result of 57 coupling constants in 20 compouds shows that there is a better agreement between the calculated and the experimental results only with few exceptions
