Description:
<jats:p>The two published electron diffraction investigations of isobutane led to slightly conflicting results. We have repeated the calculation of the theoretical scattering curves using Z—F instead of Z for the atom form factor and including the temperature factor. The final results are: C–C distance, 1.54±0.02A; C–C–C angle 111° 30′±2°.</jats:p>
