Volatility (chemistry) vapor pressure chart (right hand side) displays the vapor pressures dependency for a variety of liquids as a function of temperature. For example, at any given temperature, chloromethane (methyl chloride) has the highest vapor pressure of any of the liquids in the chart. It also has the lowest normal boiling point (−24.2 °C), which is where the vapor pressure curve (the blue line) intersects the horizontal pressure line of one atmosphere (atm) of absolute vapor pressure. Volatility (chemistry) In chemistry and physics, volatility is quantified by the tendency of a substance to vaporize. Volatility is directly related to a substance's
National Laboratory of Atomic, Molecular and Optical Physics spectroscopic databases such as HITRAN. The research of the ion group is focused on trapped molecular ions in the ion traps – relatively new branch of physics. Recent works in this field focus on the production, detection and cooling of the molecular ions. The trapped molecules are subject to spectroscopic investigations and as products/substrates for cold chemistry of single molecules. National Laboratory of Atomic, Molecular and Optical Physics National Laboratory of Atomic, Molecular and Optical Physics (KL FAMO) is the national inter-university research center with the headquarters at Institute of Physics of Nicolaus Copernicus University in Toruń, Poland.
