碱土金属双原子基团振动特性常数间的关系

The Relation Between The Vibration Force Constants And Vibration Wave Numbers Or Anharmonicity Constants Of The Alkali Earth Metal Diatomic Groups

基团(离子及分子)的红外光谱波数变化复杂。寻找其变化规律性并从基团的物理化学特性上加以阐述,是研究工作的一个重要方面。我们找到了某些碱土金属双原子基团谐振动波数及非谐性常数的规律性变化。由谐振动波数计算得力常数,发现力常数具有规律变化(少数例外)。力常数变化、谐振波数变化及非谐性常数变化基本上具有正相关性。

The vibration force constants were calculated and the regular change of them were found. The changes of vibration force constants, and of harmonicity vibration wave numbers or anharmonicity constants of the Alkali Earth Metal diatomic groups are positively interrelated.
