With measurements of the magnetic circular dichroism and band-structure calculations in the local spin density approximation (LSDA+U) approach, we revealed that the orbital moment of O in ${\mathrm{CrO}}_{2}$ is ferromagnetically coupled to that of Cr, whereas the spin moment of O is antiferromagnetically coupled to that of Cr. Spin and orbital magnetic moments of Cr and O are enhanced as Coulomb interaction energy U increases. Comparing the magnetic circular diachromism data with the LSDA+U calculations, we conclude that it is essential to include the on-site Coulomb energy for adequately describing the orbital magnetic moments of ${\mathrm{CrO}}_{2}.$

An entry from the Cambridge Structural Database, the world’s repository for small molecule crystal structures. The entry contains experimental data from a crystal diffraction study. The deposited dataset for this entry is freely available from the CCDC and typically includes 3D coordinates, cell parameters, space group, experimental conditions and quality measures.
Biphasic Cu(ii) catalyzed selective oxidative cleavage of aromatic gem-disubstituted alkenes to carbonyl compounds using tert-butyl hydroperoxide at room temperature.
Temperature dependences of the magnetic susceptibility $\ensuremath{\chi}$ and heat capacity ${C}_{p}$ of CdSe quantum dots with size $d=2.8$, 4.1, and 5.6 nm are compared to those of bulk CdSe to determine the size-dependent effects. With decreasing size $d$, the following effects are observed: (i) room temperature optical absorption shows a blueshift of the band gap; (ii) room temperature x-ray diffraction show wurtzite structure but with smaller lattice constants; (iii) magnetic susceptibility changes from negative (diamagnetic) for the bulk to positive $\ensuremath{\chi}$ with magnitude increasing with decreasing $d$; and (iv) the Sommerfeld constant $\ensuremath{\gamma}$ determined from the ${C}_{p}∕T$ vs ${T}^{2}$ data increases. Possible explanations for these size-dependent properties are presented.
