| Some organic substances may be marketed either in a specific isomeric form or as a mixture of several isomers. |
| Two isomeric substances may differ widely in their calorific constants, an observation which has repeatedly been verified. |
| Most samples contained isomeric patterns closely resembling that of the commercial formulations, with a predominance of? |
| However, the intensity pattern of these vibrations is very much alike, which points to the same isomeric structure for these photoproducts. |
| Muscarine is isomeric with betain and oxycholin, from which it is separated by its fluorescence and poisonous properties. |
| It is isomeric with etherole, and received its name from the assumption of its being the base of the ethereal compounds. |
