Consider a lattice with N spin- 1 atoms with magnetic moment μ. Each atom can be in one of three spin states, Sz=-1,0, 1. Let n-1, n0, and n1 denote the respective number of atoms in each of those spin states. Find the total entropy and the configuration which maximizes the total entropy. What is the maximum entropy? (Assume that no magnetic field is present, so all atoms have the same energy. Also assume that atoms on different lattice sites cannot be exchanged, so they are distinguishable.) |

SOLVED:A neutral macrocyclic ligand with four donor atoms produces a red diamagnetic low-spin d^8 complex of Ni(II) if the anion is the weakly coordinating perchlorate ion. When perchlorate is replaced by two thiocyanate ions, SCN^-, the complex turns violet and is high-spin with two unpaired electrons. Interpret the change in terms of structure.

A solid contains N magnetic atoms having spin ? At sufficiently high temperatures, each apin is completely randomly oriented, i.e., equally bkely to be in either of its two possible states. But at sufficiently low temperatures the interactions between the magnetic atoms causes them to exhibit ferromagnetism, with the result that all their epins become oriented along the same direction as T →0. A very crude approximetion suggests thet the spin-dependent contrihution C(T) to the heat capacity of t

A beam of silver atoms is created by heating a vapor in an oven to 1000^∘ C, and selecting atoms with a velocity close to the mean of the thermal distribution. The beam moves through a one-meter long magnetic field with a vertical gradient 10 T / m, and impinges a screen one meter downstream of the end of the magnet. Assuming the silver atom has spin (1)/(2) with a magnetic moment of one Bohr magneton, find the separation distance in millimeters of the two states on the screen. | Numerade

SOLVED: Hydrogen atoms are placed in an external 1.65-T magnetic field. (a) The protons can make transitions between states where the nuclear spin component is parallel and antiparallel to the field by absorbing or emitting a photon. Which state has lower energy: the state with the nuclear spin component parallel or antiparallel to the field? What are the frequency and wavelength of the photon? In which region of the electromagnetic spectrum does it lie? (b) The electrons can make transitions be

Planets of the Solar System: Tilts and Spins. How does your favorite planet spin? Does it spin rapidly around a nearly vertical axis, or horizontally, or backwards? This video animates NASA images of all eight planets in our Solar System to show them spinning side-by-side for an easy comparison. In the time-lapse video, a day on Earth (one Earth rotation) takes just a few seconds. Jupiter rotates the fastest, while Venus spins not only the slowest, but backwards. The inner rocky planets across t
