1. ### I Seeking better explanation of some quantum stats formulae

In "Introduction to Quantum Mechanics", Griffiths derives the following formulae for counting the number of configurations for N particles. Distinguishable particles... $$N!\prod_{n=1}^\infty \frac {d^{N_n}_n} {N_n !}$$ Fermions... $$\prod_{n=1}^\infty \frac {d_n!} {N_n!(d_n-N_n)!}$$...
2. ### I In what cases (precisely) are Hund's rules valid?

I can't find on any good source (such as a textbook) a precise specification about the cases when Hund's rules (especially Hund's third rule) for an electronic configuration of atom are valid (the rules help to select the lowest energy state of a configuration). As far as I understood: Hund’s...
3. ### I Quantum Field Configurations and Wavefunctions

Could anyone explain what a quantum field configuration is, and any relation this concept may have to the idea of a wavefunction? Perhaps for a scalar, quantum field?

### L-Idose (configuration, chirality and stereocenters)?

I'm struggling with the following problem: Draw (using Haworth notation) the L-Idose Is it chiral? Nominate every functional group Mark every stereocenter Now, I tried doing the following, but I'm quite frankly confused: which one Idose is the correct (meaning the true L-) one?
5. ### Difference in potential energy of two charge configurations

Chapter 24, Question 61 Given two configurations, ##C_1##, ##C_2## of ##N## point charges each, determine the smallest value of ##N## s.t. ##V_1>V_2##. ##C_1##: ##N## point charges are uniformly distributed on a ring s.t. the distance between adjacent electrons is constant ##C_2##: ##N-1##...
