Identification of new psychoactive substances using correlation measurement with inverse trigonometric function in forensic analysis

Abstract

The article conducted a comparative analysis of new psychoactive substances entering one party,
and samples from the party with a different chemical profile. The result of the analysis is the value of the
correlation coefficient with the inverse trigonometric function (arccos), object №1 = 0.99959887, object №2 =
0.999994361; arccos (0.99959887) = 1.623 °, arccos (0.999994361) = 0.608 °. The effectiveness of the use of the
correlation measurement (Pearson’s correlation) with the inverse trigonometric function (arccos) in a comparative
study, which is an excellent solution to the problem of modern chemistry, is proved.
