1
Q

AX
explain signal

A

a is coupled 1 thing

so u get one split

so u get a doublet

Q

AX2
explain signal

A

a is coupled to 2 things

so u split twice

but theyre the same
so they have the same cc which means they will overlap and give a high intensity where they do so.

triplet

Q

AMX

explain signal

A

A is coupled to 2 diff things

2 splits
diff things so diff cc so they dont overlap

doublet of doublets

4
Q

AMX2

explain signal

A

A is coupled to 3 diff things
one is the same,, 2 are the same

3 things but 2 diff coupling constants

3 splits
1/3 splits will overlap

doublet of triplets

Q

how to find the cc in hz

A

multipy the ppm difference by the strength of the nmr magnet

ppm x mhz will give the units in hz

Q

if the signals arent symmetric what do we not find

A

we dont find the cc between them bc theyre not coupled together,, theyre 2 different signals

Q

see the signal then what

A

draw the splitting tree
then figure out what split system it is by looking what things overlap etccc
