Multivariate statistical analysis of mid-infrared spectra for a G1 allyl-terminated carbosilane dendrimer

► New G1 allyl-terminated carbosilane dendrimer is characterized. ► FT-IR spectroscopy, PCA and 2D correlation spectroscopy were used to study the microstructural changes occurring at heating. ► The effect of temperature as a perturbing parameter gives new information about its effect on the structure and dynamics of macromolecular systems.
