Molecular Tomography of the Quantum State by Time-Resolved Electron Diffraction

Figure 2

Experimental probability density for N₂ (upper curve) in an equilibrium distribution at 673 K; note the slight asymmetry of the 𝑃(𝑟) due to the anharmonicity of the molecular vibration. Typical sampling functions (lower curves) selected for illustration. The sampling procedure was applied for 𝑛<10 and the dimensionless variable 𝑥=(2𝜋𝜇𝜔_𝑒/ℎ)^1/2(𝑟−𝑟_𝑒), where 𝜇 is the reduced mass, 𝜔_𝑒 is the harmonic frequency, and 𝑟_𝑒 is the equilibrium internuclear distance. Sampling functions for N₂ (bottom) are defined in (14).
