| Research Abstract |
In this research project, we have investigated the adsorption and ortho-para conversion of hydrogen molecules physisorbed in nano-porous surfaces. The adsorption energy was found to be enhanced as compared to those on flat surfaces. On an amorphous ice surface, the ortho-para conversion was found to take place with a time constant of 400s. To explain this unusual spin conversion, we have proposed an electric-field-induce spin conversion model.
