Webfor the deuterated iPA moiety are the amide I¢ (mainly the C=O stretch vibration of the deuterated amide group) and amide II¢ (a combination of N–D bend and C–N stretch vibrations of the deuterated amide group) bands observed at 1624 cm)1 and 1469 cm)1, respec-tively. IR bands due to the AA moiety are the C=O WebThe separation of IPA and seven kinds of deuterated IPAs were proportional to the number of labeled deuterium atoms and inversely to the temperature of the column oven. The resolution coefficient between IPA and IPA-3-C2H3-4-(C2H3)2 (IPA-2H-7) was 1.46 at 200 degrees C for column temperature.
