Raman spectroscopy investigation of various saturated monoacid triglycerides
A study of the vibrational behavior of five saturated monoacid triacylglycerides is performed by Raman spectroscopy at room temperature in the 3100–500 cm −1 spectral range. The splitting of the C O stretching mode leads to conclude on the existence of two or three geometries of C O in the “knot” gr...

−1 spectral range. The splitting of the C
O stretching mode leads to conclude on the existence of two or three geometries of C

C
O. The C
O stretching mode seems to be a good tool for distinguishing the polymorphic forms of the studied triglycerides. The assignments of the different C
H stretching modes are performed in the 1500–500
cm
−1 spectral range. The
I(2845)/
I(2880) (in the C
H stretching spectral region) and
I(1445)/
I(1296) intensity ratios (between the maximal intensity
I(1445) of the CH
2 scissoring mode and the maximal intensity
I(1296) of the skeletal vibration of
(CH

n
in-phase twist) seem to depend on the type of polymorphic forms of these molecules. |
