a, b Variable-temperature infrared spectra of VanEHBP7 upon heating from 20–150 °C (interval: 3 °C): (a) 3600-3000 cm−1 and (b) 1800−1500 cm−1. Generalized synchronous (c, e) and asynchronous (d, f) 2D correlation spectra of EN-VanEHBP7 calculated from the temperature-dependent FT-IR spectra in the regions of 3600-3100 cm−1 vs. 3600-3100 cm−1 (c, d) and 1800–1600 cm−1 vs. 1800−1600 cm−1 (e, f) red colors represent positive intensities, while blue colors represent negative intensities.
