✦ Synopsis

The electromagnetic problem has been solved for randomly oriented nonspherical and inhomogeneous structures with complex refractive indices 1.40175-2:93 Γ‚ 10 Γ€5 i (oxygenated hemoglobin) and 1.33018-2:09 Γ‚ 10 Γ€8 i (immersed in water) due to the T-matrix method. The light scattering properties of spheroidal erythrocytes for each condition were obtained using so-called Mie theory. In this study, the spheroidal erythrocyte is assumed to have a radius of 2:78 mm; giving it a volume equivalent to the average actual erythrocyte, and is illuminated by a plane wave of l ΒΌ 873 nm: The T-matrix elements are obtained by numerical integration in each condition. Comparisons for erythrocytes with oxygenated hemoglobin and immersed in water, and its results for large, randomly oriented spheroids, show that the applicability range of the scattering process depends on the imaginary part of the refractive index and is changed for different elements of the scattering matrix.

The transitions between the water-equilibrated structures of the GTP and GDP forms of Ha-ras-p21 have been calculated by using the targeted molecular dynamics (TMD) method (Schlitter et al., Mol.

## Abstract We evaluate the performance of ten functionals (B3LYP, M05, M05‐2X, M06, M06‐2X, B2PLYP, B2PLYPD, X3LYP, B97D, and MPWB1K) in combination with 16 basis sets ranging in complexity from 6‐31G(d) to aug‐cc‐pV5Z for the calculation of the H‐bonded water dimer with the goal of defining which
