An apparatus and method for extracting energy is provided. In one aspect the method includes using chemical reactions to generate vibrationally excited molecules, such as high-quantum-number-vibrationally-excited gas molecules in a region. The vibration energy in the vibrationally excited molecules is converted into hot electrons when the excited molecules contact a conductor. A geometry is provided so that the excited molecules may travel, diffuse or wander into a conductor before loosing a useful fraction of the vibrational energy. Optionally, the generating and the converting process may be thermally separated, at least in part. The short lived hot electrons are converted into longer lived entities such as carriers and potentials in a semiconductor, where the energy is converted into a useful form.

The invention discloses a measuring system of N2 molecule vibration-rotation Raman spectrum. The system comprises an emission unit and an optics reception and signal detection unit. The emission unit irradiates the atmospheric molecules by using the ultraviolet laser with extremely narrow linewidth of 354.8 nm outputted by a seed-injected solid-state laser. The optics reception and signal detection unit collects the signal of the vibration-rotation Raman spectrum produced by the N2 molecule, uses a double grating dispersion system to disperse the light in a range of 384.9-388.6 nm in space with a linear dispersion of 8.3 mm / nm, uses a linear array detector having 32 channels to distinguish and record discrete spectral line signals of O branch (rotation quantum number J=16-2) and S branch (rotation quantum number J=0-14) of N2 molecule vibration-rotation Raman spectrum, and produces inhibition better than 13 order of magnitude for the light near 354.8 nm. The system realizes the distinction and record of N2 molecule Stokes vibration-rotation Raman spectrum, and can obtain temperature information.
