WebFeb 21, 2024 · In this study we demonstrate the possibility of dual-channel operation of a microfluidic stripline NMR setup showing one- and two-dimensional 1 H, 13 C and heteronuclear NMR experiments under continuous flow. We performed experiments on ethyl crotonate and menthol, using three different types of NMR chips aiming for … WebNMR spectrum is being acquired, students are tasked with sample preparation. The 1H-1H COSY NMR spectrum of ethyl crotonate, unknown A, is shown in Error! Reference source not found.; it clearly shows the expected couplings between the CH 2 and CH 3 of the ethyl group, as well as the couplings between the alkenic protons (a mixture of 3J HH and ...
