TOTAL CROSS SECTION MEASUREMENTS FOR ELECTRON SCATTERING ON METHYL FORMATE (HCOOCH3) MOLECULE: METHYLATION EFFECT
Abstract
We present the absolute total cross section (TCS) for electron scattering from the methyl formate (HCOOCH3) molecule measured in the 10-300 eV energy range, with electrostatic electron spectrometer working in the linear transmission mode. Comparison of TCS for the HCOOCH3 molecule with that measured earlier for the formic acid (HCOOH) compound manifests the methylation effect i.e. the response of the electron scattering dynamics on replacing of the hydrogen atom in the hydroxy group in HCOOH with the methyl group (-CH3). It is also shown that the TCS for methyl formate can be estimated with simple additivity rule, using TCSs for the formic acid, ethane and hydrogen molecules. The energy dependence of determined this way TCS for HCOOCH3 and the measured values are in very good agreement above 20 eV.
