A highly efficient synthetic pathway for hypericin as well as its derivatives was achieved under mild and green conditions with high yields.

The emergency often has the characteristics of explosiveness and population diffusion.

We study the rotational energy spectrum and deformation feature of very heavy nucleus 249 Cm in the particle-triaxial-rotor model with variable moment of inertia. Such a nucleus is the unique one involving both multiband structure and high spin states and locating very near the superheavy region. By calculating the energy spectrum, we determine the configurations and quadrupole and triaxial deformation parameters β and γ of the nucleus. The calculated results indicate that the high spin band of 249 Cm is built upon the ν[620] 1 2 + configuration with deformation parameters β = 0.296 and γ = 7.5 • and the bands based on the ν[622] 3 2 + , ν[613] 7 2 + , ν[750] 1 2 − configuration respectively are also the ones with quite large axial deformation but small triaxial deformation.
