These computed molecular parameters, including dipole moment, polarizability, proton affinity, and ionization energy of volatile organic compounds (VOCs), are crucial for the identification and quantification of VOCs in chemical ionization mass spectrometry. These parameters are determined using Density Functional Theory Read more…

Ion-molecule Collision Reactions in Gas-Phase In mass spectrometry, ion-molecule reactions refer to the chemical reactions that take place between charged ions and neutral molecules within the gas phase of the instrument. These reactions can occur either before or after the Read more…
