For the 3d‐metals Ti, V, Fe, and Cu the electronic part η of the electron–phonon coupling constant is calculated in the rigid muffin‐tin approximation. Moreover for V and Cu the pressure dependence of this quantity is investigated. The results show that the correct evaluation of the angular momentum components of the electron density of states at the Fermi energy is important. Especially the density of p‐ and f‐states exhibit a strong energy dependence within the d‐bands and lead to a variation in η as one crosses the transition metal series. The non‐spherical corrections to the Gaspari‐Gyorffy formula are small.
