Final answer:
Isotopic Fractionation value (deltaC13) is the difference in the ratio of stable isotopes ¹²C and ¹³C compared to a reference substance. It is used to analyze carbon isotopes and provides insights into the origin and processes of substances.
Step-by-step explanation:
Isotopic Fractionation value (deltaC13) refers to the difference in the ratio of the stable isotopes ¹²C and ¹³C in a given substance compared to a reference substance. It is commonly used in the field of isotopic analysis, particularly in carbon isotopes. The deltaC13 value provides insights into the origin, processes, and transformations of substances based on the fractionation of isotopes. For example, deltaC13 values can help determine the sources of carbon in environmental samples or provide clues about biological and geological processes.
