Sturm

Polarographic techniques have been used by Sturm and Hans to demonstrate that certain amino-thiadiazoles and -benzthiazoles exist in the amino form (cf. also references 62, 63). This method, which involves comparison of the polarographic rdeuction potentials of the potentially tautomeric substance with those of alkylated reference compounds, has not been applied often, but may well prove to be a means to obtain qualitative information quickly. There is a possibility that the method can be modified to yield quantitative data. ...

One can show with the help of the continued fraction (8 ) and arguments which are used in the theory of sequences of Sturm s fractions, that q(x) has infinitely many poles between x = k and x = 1. The function (x) has the following properties ...
