Summarize and attribution of the main features of α-furan acrylate infrared spectroscopy. 1. Furan ring three characteristic absorption bands are as follows: ① ring C-H and skeleton stretching vibration frequency were 3130 and 1560,1480,1391cm-1; ② ring C-O-C symmetrical and asymmetric stretching vibration frequency 1075 and 1210 cm-1 respectively. ③ The C-H out-of-plane bending vibration and ring bending vibration frequency were 885 and 750 cm-1.2, respectively. The C = C stretching vibration frequency is 1641 cm-1; at 973 cm-1, the characteristic frequency of trans = C-H out-of-plane vibration is displayed. 3. Carbonyl stretching vibration frequency of 1713cm-1, 1305, 1262 and 1165cm-1 α, β-unsaturated ester C-O-C bond symmetry and asymmetric stretching vibration of the three strong absorption peak
