2.CRAMPS法による石炭中のmobile成分の構造解析

抄録

Chemical structure analysis of mobile component in coals using solid state NMR is very difficult because of mixture components (mobile and immobile). Recent modified CRAMPS is able to find chemical information of mobile component, as immobile component is removed using the difference of T_2 value. Modified CRAMPS is very powerful and useful in order to clarify the chemical structure of mobile component in coals because this component has strong relationship with the melting and softening property of coals.
