Description: Of the 26 samples collected during VA-05/1 cruise of R V Valdivia during 1972, 19 were nodules of different forms, 4 ferromanganese crusts and 3 cylindral nodules. Nodules and crusts were air dried and pulverised. In case of cylindrical-types and crust material, the clayey-calcareous filling and core materials were removed. The powder was dried at 110°C for 24 hr. Samples were digested in an autoclave 'BOMB' with a mixture of HF-HCl-HNO3. Determinations were carried out on a PE atomic absorption spectrophotometer.

Notes: Combined utilization of 1H—1H homonuclear and 1H—13C heteronuclear NMR chemical shift correlations, two-dimensional J-resolved 1H NMR measurements and homonuclear 1H double resonance experiments allowed specific assignments for both 1H and 13C NMR frequencies to be made for the tricyclic sesquiterpene cyperene. The results also provided information on the conformation of the six-membered ring of this natural product, which was recognized as a distorted chair.

Notes: The complete assignment of the 13C NMR spectrum of longifolene was achieved from double quantum coherence measurements, while combined evaluation of a 1H—13C heteronuclear chemical shift correlation diagram and a homonuclear 1H J-resolved diagram provided all proton chemical shifts. Conformational information on the seven-membered ring of the tricyclic sesquiterpene was obtained from proton chemical shift considerations.
