What is the difference between NMR and FT- NMR instrumentation?
NMR Spectroscopy Use molecule Structure FT NMR Use Different No. of mass Structure
What is the NMR spectrum of acetylacetone?
what is the litreturevalue for enthalpy of enolization
Where does water show up in a proton NMR spectrum?
about 1.6 ppm, but you don't always see it
The structure of a compound C6H14 with a base peak at m-z 43?
(CH3)2CHCH(CH3)2 in NMR
How do you interpretation a cosy nmr?
cosy is a one of 2D-NMR technique
What is the difference between NMR and FT- NMR instrumentation?
NMR Spectroscopy Use molecule Structure FT NMR Use Different No. of mass Structure
What are the Factors which cause defects in NMR spectrum?
The main factor is the presence of water. If the sample is NOT fully dried of water it will cause a big 'spike' in the spectrum .

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.
The structure of a compound C6H14 with a base peak at m-z 43?
(CH3)2CHCH(CH3)2 in NMR
What sort of structure does the spectrum of a pulse train have?
A pulse strain has a structure called a frequency comb. This is a spectrum that has a series of discrete and equally spaced elements.
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.)
How will you distinguish between chloroform and carbon tetrachloride?
Well, they smell different, but boiling point, index of refraction, NMR or IR spectrum would be safer and more reliable methods.
How is it possible to identify an element by looking at spectrum?
Each element has a unique adsorption and/or radiant spectrum. If you compare the spectrum you get with a list of known spectrums you can make a match.
How do you interpretation a cosy nmr?
cosy is a one of 2D-NMR technique
