In addition, replacing N-H group of the pyrrole ring with another substituent would eliminate some intramolecular hydrogen bonding which might also affect their macroscopic structures and NLO properties [7].
The position of this band is strongly influenced by the structure of the compounds, for example by the type of substitution pattern in the donor and the acceptor moieties.

Epoxy resins are thermosetting resins that when cured, form a highly crosslinked, glassy or crystalline structure that will not soften in the presence of heat, being degraded when submitted to excessive heat, chemical attack or mechanical stress.
The formation of the epoxy ring (oxirane ring) occurs in the double bonds present in the carbon backbone structure of the fatty acid molecules and, thus, the higher the degree of unsaturation the more oxirane rings are formed during epoxidation.
