Abstract:

Fourier transform infrared spectroscopy (FTIR) was used to measure the spectroscopic information of isoprene. Using Gaussian
03 program under density functional theory (DFT), the reaction mechanism of OH isoprene adducts were studies with abinitio methods at the
B3LYP/6-31G(d,p) level of theory for optimized geomethies and frequency calculations. Results show that the experimental results
agreed well with the theoretical values. The pathways involved in the reaction between OH and isoprene were found and the methods to
block this key reaction pathway in principle were discussed.
