Hi,
You have 2 methods:
Hdf5.GroupExists(fileorGroupId, nameOfGroup);

for example:

      string filename = @"d:\test.h5";
      var fileId = Hdf5.OpenFile(filename, true);
      var exist=   Hdf5.GroupExists(fileId, "/root/eit/d1");

for groupId:

        public static long CreateOrOpenGroup(long fileOrGroupId, string groupName)
        {

            return (Hdf5Utils.ItemExists(fileOrGroupId, groupName, Hdf5ElementType.Group))
                ? H5G.open(fileOrGroupId, Hdf5Utils.NormalizedName(groupName))
                : H5G.create(fileOrGroupId, Hdf5Utils.NormalizedName(groupName));
        }
