Alkyl C-H विश्वास 1.0
“temperature is lower than 45 °C, which is attributed to the cm-1 C-H An important absorbance peak at 1141 is usually minor influence of the diffused water on the bonds.”

Oxygen heterocycle विश्वास 1.0
“The band at 1356 cm-1 is due to C-OH stretching of O-H groups, while the band at at ~1600 can be attributed to stretching mode of the carbon skeletal network to cm-1 1045 and at 1141 cm-1 can be also attributed to epoxy and alkoxy C-O group”
