The de Broglie Wavelength

The de Broglie Wavelength

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Electron Affinity

Electron Affinity

The electron affinity (EA) is the energy change for adding an electron to a gaseous atom to form an anion (negative ion).

Intermolecular Forces

Intermolecular Forces

Atoms and molecules interact through bonds (or forces): intramolecular and intermolecular. The forces are electrostatic as they arise from interactions (attractive or repulsive) between charged species (permanent, partial, or temporary charges) and exist with varying strengths between ions, polar, nonpolar, and neutral molecules. The different types of intermolecular forces are ion–dipole, dipole–dipole, hydrogen bonds, and dispersion; among these, dipole–dipole, hydrogen...

Mass Spectrometry: Alkyl Halide Fragmentation

Mass Spectrometry: Alkyl Halide Fragmentation

Chlorine isotopes exist as 35Cl and 37Cl in a 3:1 ratio, while bromine isotopes exist as 79Br and 81Br in a 1:1 ratio. The mass spectrum of alkyl halides typically produces two distinct molecular ion peaks, the molecular ion peak, [M], and the molecular ion plus two, [M + 2] peak. The relative heights of these two peaks are proportional to the isotopic abundance ratios of the halide. For example, 2‐chloropropane and 1‐bromopropane display two peaks with relative peak heights in a 3:1 and...

Background:

Trifluorobromomethane (CF3Br) is a potential precursor for generating bromine radicals.
Accurate scattering cross sections are crucial for utilizing CF3Br in electron collision studies.
Existing experimental and theoretical data for CF3Br electron scattering are limited.

Purpose of the Study:

To present new measurements of elastic differential cross sections (DCS) for CF3Br.
To provide data for incident electron energies ranging from 15 to 50 eV.
To validate the use of CF3Br as a precursor for Br radical generation in electron collision experiments.

Main Methods:

Experimental measurement of elastic differential cross sections (DCS) for CF3Br.
Electron scattering experiments conducted at incident energies from 15 to 50 eV.
Comparison of experimental DCS with existing theoretical calculations and prior experimental data.

Main Results:

New elastic differential cross section (DCS) data for CF3Br were obtained between 15 and 50 eV.
The measured DCS show good agreement with a previous experimental study and Schwinger multichannel with pseudo potentials (SMCPP) calculations.
Derived integral elastic and momentum transfer cross sections also agree well with SMCPP results.

Conclusions:

The present DCS measurements support the use of CF3Br as a reliable precursor for generating gas-phase Br radicals.
The good agreement between experimental and theoretical data validates the scattering models used.
This work provides essential cross-section data for future electron collision studies involving CF3Br.
