Splitting Definition and 259 Threads

Wood splitting (riving, cleaving) is an ancient technique used in carpentry to make lumber for making wooden objects, some basket weaving, and to make firewood. Unlike wood sawing, the wood is split along the grain using tools such as a hammer and wedges, splitting maul, cleaving axe, side knife, or froe.

    What is the NMR splitting pattern for Butane?

    Homework Statement Butane, CH3CH2CH2CH3 has two proton environments would the splitting be 3, 6 OR 3,4 Homework Equations The Attempt at a Solution The 3 splitting would be because the CH3 group is next to a carbon with 2 hydrogens (n+1 --> 2+1 = 3) Now the 6 would be because...

    Exchange Splitting: Atomic Orbitals, Zeeman Effect & More

    I would like to understand what is "exchange splitting" in atomic orbitals. For which orbitals does it happen ? Is there any similarity between this phenomenon and the Zeeman effect (which breaks the degeneracy on the magnetic quantum number and then splits the orbital into sub-orbitals having...

    Why don't pure mathematicians like to split derivatives?

    I remembered the other day that a while back my teacher (can't remember what topic, think it was implicit differentiation) had something like dy/dx and said to us that you could times both sides of the quation by dx as long as you don't tell any pure mathematician. I was wondering why pure...

    Splitting a single light source into two out-of-phase sources?

    I've been contemplating an experiment on a 1-dimensional system which would require a single light source to be split into two separate sources which are exactly out of phase with each other.
