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.
