低温技术用于记录由视黄醇和相关化合物形成的长波长吸收电致变色物质的光谱。这些电致变色物质的形成是由碘或三氯乙酸诱导的，它们仅起酸的作用。电致变色物质是相应多烯的相应碳离子。给定多烯的碳正离子是相同的，不管它们是由碘还是三氯乙酸形成的。碳正离子的分子结构可以确定地写出来。因此，可以阐明多烯及其碳正离子中π电子系统的确切性质。
Low temperature techniques are used to record spectra of long wavelength absorbing electrochromic species formed from retinol and related compounds. Formation of these electrochromic species is induced either by iodine or trichloroacetic acid which merely act as acids. The electrochromic species are the corresponding carbonium ions of the respective polyenes. The resulting carbonium ions of a given polyene are identical regardless of whether they are formed by iodine or trichloroacetic acid. The molecular structures of the carbonium ions can be written with certainty. Consequently, the exact nature of the π‐electron system in the polyene and its carbonium ion may be elucidated.
