for a triplet. You have to take the (difference between the middle and one of the outer frequencies)* the frequency in MHZ

Why chloroform appeared as triplet in carbon 13 nmr?
Deuterium has a nuclear spin of 1; causes the C-13 signal to be split into a triplet at 77.0 ppm
In chemistry for a proton NMR what does an apparent triplet mean?
As far as I'm aware, it means that it looks like a triplet, but you don't expect a triplet. It's "really" a doublet of doublets, but the two coupling constants are too similar, so it looks like a triplet, as the two inner peaks merge.
What is the difference between NMR and FT- NMR instrumentation?
NMR Spectroscopy Use molecule Structure FT NMR Use Different No. of mass Structure
How do you interpretation a cosy nmr?
cosy is a one of 2D-NMR technique

Why does a triplet occurs in C 13 nmr spectra with CDCl3?
In this case, carbon nuclei can couple with deutrium one and the spin quantum no. (I) of deutrium is 1. So according to the famous formula to find the multiplicity of a signal (2nI+1) in NMR, it comes out to be 3 i.e. triplet.

How do you calculate the number of protons from NMR spectrum?

In NMR the value of alkynyl proton is less than the value os alkenyl proton?
When alkynyl molecules are placed in NMR instrument the induced magnetic field of molecules are in Diamagnetic region of external magnetic field. There fore the resultant energy will be low
In the H NMR spectrum why does 1 2-dichloroethane show up as a singlet and not a triplet?
The molecule is symmetric so all protons are equivilent. Equivilent protons cannot couple with each other, so the spectrum is a singlet.

Why J value for mutually coupled hydrogen atoms calculated from the NMR print out often do not match?
NMR print outs are usually rounded to three decimal places, A rounding 'error' of 0.001 will equate to a J value 'error' of 0.3 (on a 300 MHz machine.)

When was Journal of Biomolecular NMR created?
Journal of Biomolecular NMR was created in 1991.
