Conformational stability and conformation specific photochemistry and complexation has been studied for aromatic amino-acids in the gas phase by laser spectroscopy and quantum chemical calculation. The study has been extended to reveal the mechanism of the encapsulation of guest molecules by functional molecules, such as calixarene and crown-ether. Finally, a new mass-spectrometry combined with laser desorption has been developed to study the structures of nonvolatile molecules, such as bio-related molecules and functional molecules having large molecular weight.

用激光光谱和量子化学计算研究了芳香族氨基酸在气相中的构象稳定性和构象特异性光化学及络合作用。该研究进一步揭示了杯芳烃、冠醚等功能分子对客体分子的包封机理。最后，发展了一种新的质谱结合激光解吸的方法来研究非挥发性分子的结构，如生物相关分子和具有大分子量的功能分子。
