In our latest publication in Chemical Communications, we present a breakthrough in understanding spin-spin coupling constants (SSCC) in organofluorine compounds. Our study emphasizes the need for a nuanced approach to interpreting SSCC, shedding light on how substituent effects can significantly alter SSCC transmission mechanisms. This discovery challenges conventional wisdom and urges a reevaluation of current methodologies. We also highlight the importance of benchmark calculations, advocating for a meticulous comparison between experimental and theoretical data for accurate SSCC interpretation. Our research aims to broaden the scientific community’s understanding of SSCC, offering new perspectives and guidance in organofluorine chemistry. This paper marks a significant step towards deeper insights into the complexities of molecular interactions. Check it out in Chem. Comm:
