Fragmentation – Fragmentation of diastereoisomers (cis-decalin II)
Fragmentation – Fragmentation of diastereoisomers (No ring fragmentation)
Fragmentation – Fragmentation of diastereoisomers (Trans-decalin I)
Fragmentation – Fragmentations are controlled by stereochemistry
Fragmentation – Fragmentations are controlled by stereochemistry (Cis isomer)
Fragmentation – Fragmentations are controlled by stereochemistry (Trans isomer)
