Since these algorithms were based on libraries of molecular fragments and their characteristic spectral features, they turned to predicted 13C NMR spectra of candidate structures to differentiate them. These early CASE systems were also challenged by the output of multiple equally probable structures. However, these systems were still limited to relatively small and simple structures and were not nearly as reliable as modern CASE systems. As the field of spectroscopy evolved and scientists began taking advantage of the increased amount of structural information in 1D NMR data, CASE algorithms also pivoted to rely more heavily on the data from 1H and 13C NMR. The first CASE method from the 1968 publication described the use of computers to determine the structure of an unknown from infrared spectroscopy data.

In fact, experts believe that, similarly to how a processing software is now used in the analysis of all analytical data today, CASE will be used in every structure elucidation in the not-so-distant future.
While CASE systems will never fully replace a scientist, they can be of benefit to those performing structure elucidations of every level. With commercially available CASE systems such as ACD/Structure Elucidator, an increasing number of scientists are turning to these tools for a fast and unbiased answer to even their most challenging structure elucidations. Modern CASE expert systems can now elucidate the structures of large and complex natural products in far less time than it would take even the most advanced spectroscopists. The first CASE systems were limited to simple small molecules. Since its introduction, with significant advances in both the fields of computer science and spectroscopy, CASE has also come a long way.
In 1968, Mikhail Elyashberg and Lev Gribov published the first CASE method.
