Macdonald, 'Reinterpreting and Augmenting John Tyndall's 1859 Greenhouse Gas Experiment with Thermoelectric Theory and Raman Spectroscopy', viXra:1504.0165 (v1 21 Apr 2015, v3 15 Dec 2015), 32 pp. [web] https://vixra.org/abs/1504.0165 Abstract, in brief: argues that thermopile detectors "discriminate" between dipolar gases and the control and so "misinterpreted IR absorption"; that N2 and O2 have vibrational modes (1556 and 2330 cm-1, Raman-active) and so are also "greenhouse gases"; "all substances have thermal absorption properties, as measured by their respective heat capacities". Priority 3 (related work contesting the standard reading of Tyndall's experiment). Recorded as the author's claim; viXra is an unrefereed repository (its own disclaimer). The physicist should weigh it: the point on which it turns is the difference between Raman activity and infrared activity (a vibration needs a changing dipole moment to absorb infrared), which is the modern form of Tyndall's own "elementary gases are transparent" result (claim 1).
