And what's the value of DISTCUT for the output posted?

Try:
Code:
awk '{atom[NR]=$3;xi[NR]=$6;yi[NR]=$7;zi[NR]=$8}
END{
for(i=1;i<=NR;i++)
 for(j=1;j<=NR;j++)
 {
  if(j==i) continue
  dist=sqrt((xi[i]-xi[j])^2 + (yi[i]-yi[j])^2 + (zi[i]-zi[j])^2)
  if(dist!=0 && dist<=cutoff)
   print atom[i],atom[j],dist
 }
}' cutoff="$DISTCUT" sub_oxy_high > oxy_dist_all

xlsatoms

xlsatoms(1X)															      xlsatoms(1X)

NAME

       xlsatoms - list interned atoms defined on server

SYNOPSIS

       xlsatoms [-options...]

OPTIONS

       This  option  specifies	the X server to which to connect.  This option specifies a printf-style string used to list each atom <value,name>
       pair, printed in that order (value is an unsigned long and name is a char *).  xlsatoms will supply a newline at the end of each line.  The
       default	is  %ld	%s.  This option specifies the range of atom values to check.	If low is not given, a value of 1 assumed.  If high is not
       given, xlsatoms will stop at the first undefined atom at or above low.  This option specifies the name of an atom to  list.   If  the  atom
       does not exist, a message will be printed on the standard error.

DESCRIPTION

       The  xlsatoms  command lists the interned atoms.  By default, all atoms starting from 1 (the lowest atom value defined by the protocol) are
       listed until unknown atom is found. If an explicit range is given, xlsatoms will try all atoms in the range, regardless of whether  or  not
       any are undefined.

ENVIRONMENT

       to get the default host and display to use.
