分子の核スピン異性化とクラスター化に関するテラヘルツ・赤外分光研究

Terahertz and infrared spectroscopic investigation on nuclear spin isomerization and clusterization of molecules

山川 紘一郎   

Yamakawa, Koichiro

核スピン異性化と水素結合クラスターの形成という、プロトンの関与する量子現象の研究を行った。その場テラヘルツ・赤外吸収分光法と第一原理振動計算を組み合わせることで、水素,水,メタン分子の核スピン異性化速度と、水クラスターの分子間振動モードを決定した。

I have investigated the proton-related quantum phenomena: nuclear spin isomerization and hydrogen-bond clusterization. With use of in situ terahertz and infrared absorption spectroscopy combined with ab initio vibrational calculation, I determined the nuclear spin conversion rates of H$$_{2}$$, H$$_{2}$$O, and CH$$_{4}$$ as well as the intermolecular vibrational modes of water clusters.
