In the past … WebStable isotopes partitioning between two substances A and B can be expressed by the use of the isotopic fractionation factor (alpha): αA-B = RA/RB where R is the ratio of the heavy to light isotope (e.g., 2 H/ 1 H or 18 O/ 16 O). Values for alpha tend to be very close to 1. [1] [2] Types [ edit]
