Note that triplet at 6.001 ppm and a triplet at 6.002 ppm can be distinguishing Chemistry Science Organic chemistry CHE MISC WebThe Curphy-Morrison table is used to calculate the chemical shift of protons bonded to sp 3 carbons. Determine the type of proton to be calculated (CH 3, CH2, or CH) and use the appropriate base shift. Then add corrections for all substituents at the and carbons: e.g. for a CH2 group use 1.2 as base shift, and select parameters from the
