Spectra of ethyl acetate
1H NMR spectrum
- Triplet d ~ 1.3 ppm ; relative intensity 3; assigned to CH3 part of ethyl group, triplet splitting due to neighbouring CH2.
- Singlet d ~ 1.9 ppm ; relative intensity 3; assigned to CH3 part of acetyl (ethanoyl) group, no splitting as no hydrogens attached to adjacent carbon
- Quartet d ~ 4.1 ppm ; relative intensity 2; assigned to CH2 part of ethyl group, quartet splitting due to neighbouring CH3.
Principal characteristic peak is n C=O at 1710 cm-1; also n C-O at ~ 1240 cm-1
Peaks at m/e 88 (M+); 73 ((M-CH3)+); 43 ((M-OCH2CH3)+);
