How do you get proton decoupled spectra of 13C NMR?
There should be a button that lets you do this very easily. There is on a Brukker 400MHz NMR.
What is the melting point of 2'4'6-trimethylquinoline?
I measured 66°C but i think my product wasn't totally pure. I've to check on my NMR spectra
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.
Why does the metal hydride in H-NMR spectra give signal at different field as compared to organic protons?
The hydride on a metal is more shielded compared to organic protons. The reason is the increased electron density associated with hydrides causes there shift to be at lower ppms compared to organic protons.
Is NMR a solvent extraction technique?
NMR stands for Nuclear Magnetic Resonance. It's an analytical/spectrographic technique based on the Zeeman effect.

The 1h and 31p nmr spectra of trimethyl phosphate are given below rationalise the appearance of both spectra?
the 1H nmr is a doublet and the splitting must arise from the 3 bond coupling between protons and phophorus

Where does water show up in a proton NMR spectrum?
about 1.6 ppm, but you don't always see it

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
What is the difference between 500 MHz and 400 MHz NMR?
basically, the higher the MHz value, the stronger the magnet, meaning less distortion and cleaner spectra.
