Abstract

Chemical shifts of all protons at 8.46 T and ^13^C atoms are presented for substituted 7′‐aryl‐7′‐apo‐β‐carotenes, where aryl = C~6~H~5~, 4‐C~6~H~4~NO~2~, 4‐C~6~H~4~OCH~3~, 4‐C~6~H~4~CO~2~CH~3~, C~6~F~5~ and 2,4,6‐C~6~H~2~(CH~3~)~3~. Assignments were established by NOE, COSY, HMBC and HETCOR studies.
