C-O (Ester)	Stretching	1300-1000	Strong	Multiple peaks expected; Complex region due to multiple C-O bonds.
C-H (Aliphatic)	Stretching	3000-2850	Medium	Multiple peaks corresponding to different types of C-H bonds.
C-H (Aliphatic)	Bending	1470-1450 & 1380-1360	Medium	Associated with CH2 and CH3 groups.
C-C (Skeletal)	Stretching	1200-800	Weak to Medium	Difficult to assign specifically without further analysis.
