Block pointed out that, if γT2 = T1γ² = [const] as would be the case for termal broadening of the Sn isotopes, that our isotope identification would be backwards, since it turns out that
dv/dΔω hmax = -γ²([const.])T2²
[Now it] T2 = 1/γΔH and ΔH = kH, then T2 = 1/γkH = 1/kΔω & since we compare at [const.] freq, T2 = [const] [therefore] our γ² correction is correct on opposite page.
