what is beter for research NMR or Mass_spectrum in spectro chemistry?

Answer 1

That depends on your research study. Use NMR to obtain physical, chemical, electronic and structural information about a molecule. This is the only technique that can provide detailed information on the exact three-dimensional structure of biological molecules in solution.

Mass spectrometry on the other hand, is used to measure the mass-to-charge ratio of ions. It is most generally used to find the composition of a physical sample by generating a mass spectrum representing the masses of sample components. It can also be used in these applications:

-identifying unknown compounds by the mass of the compound molecules or their fragments
-determining the isotopic composition of elements in a compound
-determining the structure of a compound by observing its fragmentation
-quantifying the amount of a compound in a sample using carefully designed methods (mass spectrometry is not inherently quantitative)
-studying the fundamentals of gas phase ion chemistry (the chemistry of ions and neutrals in vacuum)
-determining other physical, chemical or even biological properties of compounds with a variety of other approaches

The boastful Worms Celine Dion i think of i've got have been given a weigh down on Celine Dion the way she beats her chest while she sings a love song there is something approximately her makes me % to feed her and that i might like to be Mister Celine Dion She'll sing a song in English, and he or she'll sing en francais the two the songs will suck, yet i like her besides She's crammed with emotion, i'm crammed with devotion For Celine and that i'll be hers sometime Oh Celine Dion, you mushy-rock my international won't you please be mine Celine i might do something, in case you would be my woman Oh, be my woman Celine I despatched you enjoying cards and letters, yet you do no longer respond You play annoying to get, yet my coronary heart is going on and on (and on and on, etc...) I only wanna say, je aimerez and that i'm able to work out your place from my van Oh Celine Dion, you mushy-rock my international won't you please be mine Celine i might do something, in case you would be my woman Oh, be my woman Celine Celine Celine Her pores and skin's so mushy and sparkling only like porcelain I prefer she'd slather me With a bathtub of Vaseline (That replaced right into a splash creepy) i'm sorry, Celine Celine Celine Celine Dion

Answer 3

Simply:

NMR is more accurate; Mass spectrum is simpler and faster.

Answer 4

neither one is 'better'........it depends on what kind of research you are doing and what applications you are using
