| Likewise, isotopically substituted lipid membranes can be differentiated from protein adlayers and even each other with the proper selection of unique isotopic labels. |
| Ardi was excavated between 1994 and 1997 and has been isotopically dated at 4.4 million years old. |
| With its origin in the local electron distribution, the chemical shift is a sensitive reporter of the chemical environment of isotopically labeled atoms. |
| A variety of time scales has been used for assigning isotopically dated rocks to the appropriate subdivision or time unit of the Phanerozoic and Precambrian time scales. |
| Production of isotopically labeled peptides for NMR spectroscopy. |
| During interglacial periods the ice caps melt and return the isotopically light water to the oceans, where it mixes rapidly. |
