ATIR-FT-IR Spectrum of (3E)-3-(4-Chlorobenzylidene)-1,3-dihydro-2H-indol-2-one

ATIR-FT-IR Spectrum of (3E)-3-(4-Chlorobenzylidene)-1,3-dihydro-2H-indol-2-one


Interpretation of ATIR-FT-IR Spectrum of (3E)-3-(4-Chlorobenzylidene)-1,3-dihydro-2H-indol-2-one:

ATIRFT-IR Wave Number (cm-1)AssignmentRemarks
3139N-H stretching vibration
(v(N-H) (1o amide)
Symmetrical stretching vibrations of the NH group in the region 3190-3170cm-1
3078Aromatic C-H stretching vibration (v(C-H)C-H aromatic stretching in the region 3100-3000cm-1
3023Aryl-HOften obscured and appears on the region 3010-3040cm-1
2963C-H stretching vibrationsDue to CH3 group in the aromatic ring.
2899C-HSaturated C-H stretching at the region 2840-2930cm-1
1700C=O stretching vibration (v(C=O)Attributed to the carbonyl functional group and shows strong bands at 1650-1900cm-1.
1612Aromatic ringsDue to presence of aromatic ring
737C-HC-H out of plane deformation shows ortho-disubstituted benzene ring on the region 770-735cm-1
668C-ClDue to the presence of C-Cl bond shows band on the region 800-600cm-1
