Mass spectrometry measures mass-to-charge ratios (m/z) of ions; determines molecular weight and fragment composition.

ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |

  1. 1Input mass spectrum peaks and intensities
  2. 2Identify molecular ion, fragments, and base peak
  3. 3Determine molecular structure

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
Molecular ion m/z = 88, base peak m/z = 73 (M-15, loss of CH₃)
ଫଳ
Suggests methyl group loss

ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ

  • Misidentifying molecular ion (not always M⁺)
  • Not accounting for isotope patterns

What's base peak?

Most intense peak; usually stable fragment ion; useful for structure determination.
