Experimental results are interpreted, which were obtained by tip enhanced Raman Spectroscopy (TERS) in a specific SNOM (Scanning Near-Field Optical Microscope) STM (Scanning Tunneling Microscope) configuration with a tunnel gap. The interpretation is performed in terms of a classical physical model of a photon as a vacuum phonon polariton. The metal tip is considered as a conductive infinitely thin shell of a diamagnetic electron gas. The stationary single electron tunnel current of an electron tunnel passage frequency f tunnel carries not the charge e but is shown to carry an energy hfe and an isotropic orbital angular momentum h/4π which corresponds to an isotropic transversal electron spin density of an angular frequency 2π2fe.Raman Spectroscopy, Electron Spin, Photon Spin, relativistic Quantum mechanicsThe electron spin current corresponds to an isotropic azimuthal inertial torque which acts on the photon by an increase of its energy and torque. Neglecting the influence of thermal and radiative losses of the conductive shell, the interpretation reproduces the spectroscopic results within the uncertainty of the experimental results. The photoelectric Raman spectrum of the tunnel gap can be regarded as a complex admittance spectrum which depends in a nonlinear way on the tunnel voltage, the tunnel current and the wavelength of the scattered light. The conical tunnel gap configuration can be considered as a bipolar Electro-Galvanic Spin -Orbit Transformer (SPOT) and from a thermodynamic viewpoint as a Quantum Energy Converter
