A and b have the same ring structure except That a has an additional (whatever). From the (whatever)' one can see, during the (whatever) process, A got a opened ring while b's is closed. It is reasoned that the (whatever) effect the (whatever) behavior of that structure. ÖÊÆ×µÄ²»¶® |

The ring structure of A was the same as that of B, whereas, A had an additional hydroxyl group on structure. From the mass spectrogram, it showed that the ring structure of A was broken and B not, during the schizolysis process, maybe, the mass spectrometry behavior of the structure was affected by the hydroxyl group. ½ö¹©²Î¿¼£¬Ï£Íû¶ÔÄúÓаïÖú¡£¡£¡£ |
