Preferred Label : retardation factor;
Detailed label : retardation factor in planar chromatography, RF;
IUPAC definition : Ratio of the distance travelled by the centre of the spot to the distance simultaneously
travelled by the mobile phase: \[R_{{F}} \frac{b}{a}\] By definition the R F values
are always less than unity. They are usually given to two decimal places. In order
to simplify this presentation the hRF values may be used: they correspond to the R
F values multiplied by 100. Ideally, R F values are identical to the R values used
in column chromatography.;
