2e. Morphological Analysis. The morphology can be analyzed through the sphericity (𝑆) of the nanoparticle in question . 𝑆 can be calculated at any instant in time through quantitative analysis of the moment of inertia tensor. Diagonalizing this tensor yields the principal moments and axes of inertia through the eigenvalues and eigenvectors respectively. Specifically, 𝑆 is given by the ratio of the minimum and maximum eigenvalues of the moment of inertia tensor as shown in equation ( ):
