Specific Measurements:

CHClF2 (difluoromethane, HCFC-22) (mole_fraction_of_hcfc22_in_air): Mole fraction is used in the construction mole_fraction_of_X_in_Y, whereX is a material constituent of Y. A chemical species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. The chemicalformula for HCFC22 is CHClF2. The IUPAC name for HCFC22 is chloro-difluoro-methane.

C2H3Cl2F (1,1-dichloro-1-fluoroethane, HCFC-141b) (mole_fraction_of_hcfc141b_in_air): Mole fraction is used in the construction mole_fraction_of_X_in_Y, whereX is a material constituent of Y. A chemical species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. The chemicalformula for HCFC141b is CH3CCl2F. The IUPAC name for HCFC141b is 1,1-dichloro-1-fluoroethane.

C2H3ClF2 (1-chloro-1,1-difluoroethane, HCFC-142b) (mole_fraction_of_hcfc142b_in_air): Mole fraction is used in the construction mole_fraction_of_X_in_Y, whereX is a material constituent of Y. A chemical species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. The chemicalformula for HCFC142b is CH3CClF2. The IUPAC name for HCFC142b is 1-chloro-1,1-difluoroethane.
