The Infrared Absorption of Some Organic Liquids Under High Resolution Part II

The study of the C-H vibrations bands, which occur in organic liquids between $3.0\mu$ and $4.0\mu$ has been continued and extended. A more powerful spectrometer, with which wave-lengths can be determined as accurately as $\pm 0.001\mu$, has been developed for this work. Values are given here for water-vapor, benzene and toluene.
