# split.unfractured_at_index

`abjad.tools.split.` `unfractured_at_index`(container, i)

  Split container in two just before index i.

  - Leave spanners in tact.
  - Preserve parentage.
  - Resize resizble containers.
  - Preserve any container multiplier.
  - Preserve any meter denominator.

  Example. Split binary measure and leave spanners in tact:

      abjad> t = Voice(RigidMeasure((3, 8), construct.run(3)) * 2)
      abjad> pitchtools.diatonicize(t)
      abjad> p = Beam(t[:])
      abjad> print t.format

      \new Voice {
                      \time 3/8
                      c'8 [
                      d'8
                      e'8
                      \time 3/8
                      f'8
                      g'8
                      a'8 ]
      }

      abjad> split.container_unfractured(t[1], 1)
      abjad> print t.format

      \new Voice {
                      \time 3/8
                      c'8 [
                      d'8
                      e'8
                      \time 1/8
                      f'8
                      \time 2/8
                      g'8
                      a'8 ]
      }
