Other weak and narrow band maxima are found at 2880 [cm.sup.-1] (vsC[H.sub.3]) and over the C-O vibrations region 1300 to 900 [cm.sup.-1], whereas the weak-to-moderate [delta][H.sub.2]C=C band with the lineshape having a rapid slope and the maximum being positioned at 896 [cm.sup.-1] clearly occurs only in dammar resin. However, the other bands due to the carbon-carbon double bonds vibrations do not appear in reflection mode.
Moreover, the weak first overtone band of the vC[H.sub.2] cyclic is found at 6100 [cm.sup.-1] in dammar resin, while it is not clearly visible in mastic because of its marked spectral noise.
