Experiment 11: NUCLEAR MAGNETIC RESONANCE SPECTROSCOPY
• By splitting pattern, we are referring to whether a signal is showing up as a singlet, doublet, triplet, quadruplet, quintuplet or multiplet • The splitting pattern (or multiplicity) reflects the number of protons on the adjacent atom The number of peaks equals the number of protons on the adjacent atom plus one This is commonly

Doublet of Doublets Description: A doublet of doublets (dd) is a pattern of up four lines that results from coupling to two protons (or other spin 1/2 nuclei) The lines are of all equal intensities (or close to equal intensities)

downfield from TMS as an internal standard The letters s, d, t, q, and m are used to indicate singlet, doublet, triplet, quadruplet, and multiplet, respectively 1H NMR strength assays were measured using > 99 w/w tetra-chloronitrobenzene as standard Reaction monitoring was performed using
Continuous Flow Synthesis of Terminal Epoxides from Ketones
downfield from TMS as internal standard The letters s, d, t, q, and m are used to indicate singlet, doublet, triplet, quadruplet, and multiplet, respectively GC-FID analysis was performed on a ThermoFisher Focus GC with a flame ionization detector, using a TR-5MS column (30 m × 0 25 mm ID × 0 25 μm) and helium
